   Rainforest Animals: Sloths, Toucans & More

   In this episode of The Brain Bus: Tiny Explorers, your 2–4 year old will discover that a sloth moves so slowly that tiny green plants actually grow on its fur - and that this slowness is its superpower. The episode runs about 11 minutes and takes children on a layer-by-layer journey through the rainforest, from the sunlit treetops all the way down to the river's edge. It's a warm, unhurried listen built specifically for the Tiny Explorers age band. Starting up in the tree canopy with toucans and hummingbirds - the only birds that can fly backwards - children move down through the forest layers to meet a morpho butterfly, a green-furred sloth, a swimming jaguar, and the cassowary of Australia's Daintree rainforest. Along the way, tiny listeners shout quiz answers aloud, copy a sloth's slow-motion movement, and belt out their best howler monkey call. This makes a natural screen-free quiet time activity for the car, and works well as a toddler podcast or preschool podcast for families on the go. The episode closes with a gentle reflection that every creature - and every child - has their own special spot. What You'll Discover:• A toucan's enormous colourful beak is mostly hollow air, which makes it surprisingly light• Hummingbirds are the only birds in the world that can fly backwards• Sloths move so slowly that algae - tiny green plants - grow right on their fur, helping them hide• The cassowary, a tall blue-necked bird in Australia's Daintree rainforest, helps new trees grow by dropping seeds as it walks• The Kuku Yalanji people have cared for the Daintree rainforest for thousands and thousands of years All rainforest animals are introduced with warmth and wonder - the jaguar's hunting ability, for example, is noted only as a love of swimming - so the episode is gentle enough for unsupervised car listening with toddlers and preschoolers. The 'Rainforest Bodies' movement game - where kids do a slow-motion sloth stretch and then let out their loudest howler monkey call - lands perfectly in a car seat, which means backseat noise is entirely by design.

   Where Food Comes From: Farm to Fork

   In this episode of The Brain Bus: Tiny Explorers, your 2–4 year old will discover that chocolate starts as beans on a real tree, that a cow's clever tummy turns green grass into white milk, and that bees visit millions of flowers to fill just one jar of honey. It's a warm, gently paced listen designed for little minds - about 13 minutes, which fits neatly into any car trip. Nova guides the whole journey in her reassuring, curious way. This episode takes toddlers on a sensory journey from soil to table, following carrots hidden underground, cows munching in sunny paddocks, and cacao beans ripening on tropical trees. Little ones shout answers during a true-or-false quiz, play a call-and-response game called UP HIGH or DOWN LOW, and land in a calming quiet moment at the end - making it a reliable choice for screen-free quiet time in the car. The episode also shares two real cultural traditions: the Yolŋu practice of gathering sugarbag honey in Arnhem Land, and the Haudenosaunee Three Sisters method of growing corn, beans, and squash together as friends. Whether you're searching for a toddler podcast that genuinely holds a two-year-old's attention or a preschool podcast with something new for the grown-ups too, this episode earns its place in the playlist. What You'll Discover:• Carrots, potatoes, and peanuts all grow underground - a farmer pulls them up by their leafy tops• A cow eats green grass and her body turns it into milk• Chocolate begins as beans inside a bumpy fruit on a tropical tree, which are then roasted and pressed• Bees collect juice from millions of flowers to make a single jar of honey• A pineapple grows low on a spiky plant and takes almost two whole years to ripen Every topic in this episode is handled with warmth and wonder - there is nothing scary or overstimulating, and the closing Quiet Beat segment is specifically designed to bring energy gently down, making it suitable for unsupervised car listening with very young children. The UP HIGH or DOWN LOW game is made for the backseat - kids just shout their answers, no hands or screens needed, and the wondering question at the end ('what's YOUR favourite food?') keeps the conversation going long after the episode finishes.

   African Safari: Elephants, Giraffes & Big Five Facts

   In this episode of The Brain Bus: Tiny Explorers, children discover that hippos produce their own pink sunscreen right through their skin - and that a baby elephant can already walk on the day it is born. It is about 13 minutes of gentle, screen-free listening shaped specifically for ages 2–4. Nova takes little listeners on a quiet, vivid journey across the African savanna, introducing elephants, giraffes, cheetahs, hippos, zebras, and meerkats through simple language and warm sound design. Along the way, children hear a retelling of a traditional Maasai story about caring for animals and the land. A short quiz and a movement-based road challenge give kids something active to do in the back seat - making this a natural fit for screen-free quiet time on a long drive. Parents searching for a preschool podcast or a podcast for 2 year olds that holds attention without a screen will find the pacing and repetition in this episode well-matched to how young children absorb new ideas. What You'll Discover:• A baby elephant is born nearly as heavy as a grown-up person and can walk on its first day• Giraffes have hearts as big as a watermelon to pump blood all the way up their long necks• Hippos produce a pink, gooey substance through their skin that acts as natural sunscreen• The Maasai people of Kenya and Tanzania have lived alongside savanna animals for hundreds of years• No two zebras have exactly the same stripe pattern - just like fingerprints All animals are introduced with warmth and wonder - predators like the cheetah are mentioned only in the context of their amazing bodies, never in a frightening way, making this episode comfortable for unsupervised car listening with 2–4 year olds. The road challenge invites kids to wiggle their nose like an elephant's trunk, stretch their arms like a giraffe's neck, and curl up like a sleepy lion cub - which means tiny passengers stay engaged right until the next exit.

   Triceratops & Stegosaurus: Plant-Eating Dinosaurs

   In this episode of The Brain Bus: Tiny Explorers, your two-to-four-year-old discovers that some of the biggest dinosaurs that ever lived spent their days munching plants - and carried horns, spikes, and bony armor to stay safe. It's about 11 minutes of gentle, fact-grounded listening designed specifically for the youngest Explorers. Your child meets Triceratops - as long as a school bus, with three horns and a parrot-like beak for snipping leaves - and Stegosaurus, whose four tail-spikes have a real scientific name: the thagomizer. Along the way they discover that these two dinosaurs never actually met, because millions of years separated them. Whether it's screen-free quiet time on a long drive or a toddler podcast ritual before naptime, this episode keeps little hands busy with a Triceratops horn mime and a question to ask the grown-up in the front seat. It's a preschool podcast episode built around wonder, repetition, and genuine facts that hold up. What You'll Discover:• Triceratops had three horns - two above its eyes and one on its nose - and a wide bony frill around its neck• Stegosaurus had a row of bony plates along its back and four tail spikes scientists call the thagomizer• Triceratops and Stegosaurus never lived at the same time - millions of years separated them• Some plant-eating dinosaurs swallowed rocks to help mash up the plants in their stomachs• A Triceratops skull alone could be as tall as a grown-up, most of it taken up by the frill All content is calm and age-appropriate - large dinosaurs are framed as gentle plant-eaters, protective features like horns and spikes are explained matter-of-factly without any threat or fear, and the episode closes with a slow, reassuring quiet beat designed to settle rather than excite. The road challenge - holding up two pointer fingers as Triceratops horns and chomping an imaginary fern - works perfectly in a car seat and gives little ones something to do with their hands for the last stretch of a drive.

   Animal Records: Biggest, Smallest & Fastest Animals

   In this episode of The Brain Bus: Tiny Explorers, children aged 2–4 discover that a blue whale's heart is large enough for a small child to fit inside, that a bird exists which is smaller than their thumb, and that the fastest animal in the sky falls faster than a race car. Each concept is delivered gently at a pace designed for toddler attention spans, across roughly 15 minutes of screen-free listening. Nova guides little listeners through three record-breaking animals - the blue whale, the bee hummingbird, and the cheetah and peregrine falcon - using body-scale comparisons a 2–4 year old can actually picture: three school buses, a thumb, a bendy back like a spring. Children wiggle their thumb like a hummingbird and sway their arm like a whale in the Road Challenge, making this a great preschool podcast activity for longer drives. A short three-question quiz reinforces what they've heard, and a calm Quiet Beat closes the episode with a moment of stillness. Naturally suited to screen-free quiet time in the car, the episode leaves children with a wondering question they can think about all the way to their destination. What You'll Discover:• A blue whale is longer than three school buses lined up end to end, and its heart is large enough for a small child to fit inside• The bee hummingbird - the world's smallest bird - is tinier than a human thumb and its wings beat too fast to see clearly• The cheetah is the fastest animal on land, while the peregrine falcon is even faster when diving from the sky• A giraffe is tall enough for its head to touch the top of a house, and an elephant's trunk is precise enough to pick up a single peanut• Animals come in all different sizes and speeds, and each one is exactly suited to its own life All animal facts are presented with warmth and wonder - there is no predator-prey content, no scary scenarios, and the episode closes with a calm, reflective Quiet Beat that is comfortable for unsupervised car listening. The Road Challenge asks children to wiggle a 'thumb-bird' and slowly sway an 'arm-whale' - a gentle seated activity that works perfectly while buckled in.

   Rainbows & Light: What Hides Inside Sunshine

   In this episode of The Brain Bus: Tiny Explorers, children aged 2–4 discover that white sunlight has every color of the rainbow hiding inside it - and that raindrops are what pull those colors apart. It runs around 15 minutes and is designed for little listeners in the car seat. Nova guides tiny explorers through the science of rainbows in gentle, picture-book language - from the idea that sunlight is like all the crayons squished into one, to the reason a rainbow always shows its colors in the same order. Kids learn that a rainbow is actually a full circle, that you can never walk to its end, and hear the Irish story of why leprechauns hide gold there. Perfect as a screen-free quiet time activity on a long drive, this toddler podcast episode gives even the youngest listeners real facts wrapped in warmth. A road challenge invites everyone in the car to name an imaginary new color, making it a genuinely shared family moment. What You'll Discover:• White sunlight contains every rainbow color hidden inside it• Raindrops bend and separate light to reveal those colors• Rainbow colors always appear in the same order: red, orange, yellow, green, blue, purple• A rainbow is actually a full circle - we only see the bottom half from the ground• You can never reach the end of a rainbow because it moves as you walk toward it All concepts are introduced through gentle imagery and repetition suited to ages 2–4, the leprechaun folklore is framed warmly and respectfully as an Irish story passed down over generations, and there is nothing in this episode that requires a parent to be present to manage. The road challenge - naming an imaginary color nobody has ever seen - works especially well when the whole car plays along together at a red light or on a long stretch of highway.

   Chocolate: From Cocoa Pod to Bar - How It's Made

   In this episode of The Brain Bus: Tiny Explorers, children ages 2–4 discover that chocolate begins as a bitter white seed inside a bumpy, football-shaped fruit growing right on a tree trunk - not on its branches. Nova walks little ones through the full bean-to-bar journey, step by careful step, in under 20 minutes of screen-free listening. It's a genuinely surprising origin story, even for adults. Your child will travel with Nova to a hot, rainy cocoa forest, crack open a colourful pod, and follow the seed all the way to a chocolate bar - resting under banana-leaf blankets, drying in the sun, roasting in a warm oven, and being stirred into smooth liquid chocolate. The episode also introduces children to the Olmec, Maya, and Mexica peoples who cherished cacao for thousands of years - and the fact that cacao seeds were once used as money. Perfect as a screen-free quiet time activity or a toddler podcast for the car, this episode suits ages 2–4 and includes a gentle quiz, a cosy visualisation exercise, and an open-ended wondering question for the whole family to answer together. What You'll Discover:• Cocoa pods grow directly out of the trunk of the cocoa tree - not on its branches - and can be yellow, orange, red, or purple• Freshly picked cocoa seeds taste bitter, not sweet, and go through several steps - resting, drying, roasting, and stirring - before they become chocolate• The Olmec people were among the very first to use cacao, over three thousand years ago, and many Maya people still value it today• The Mexica people (sometimes called the Aztec people) valued cacao seeds so highly they used them as money• One cocoa pod is roughly the size of a small football and contains the seeds that eventually become a chocolate bar All content is calm and age-appropriate for 2–4 year olds - the episode uses warm, gentle language throughout, the history of ancient peoples is introduced respectfully and simply, and there is nothing intense or overstimulating, making it safe for car listening without supervision. The Segment 5 visualisation - where Nova invites children to imagine being a tiny cocoa seed on its journey - works especially well in the car, where little ones are already sitting still and can close their eyes and wiggle their fingers on cue.

   Nocturnal Animals: Life After Dark - Owls, Bats & Tarsiers

   This episode of The Brain Bus: Tiny Explorers introduces children aged 2–4 to the world of nocturnal animals - including the tarsier, a tiny creature whose eyes are each bigger than its own brain. The episode runs around 15 minutes and is designed to hold a young child's attention gently from the first hoot to the final sign-off. It's a warm, unhurried listen built for little ones. Nova guides Tiny Explorers through the nighttime world, meeting owls that fly in total silence, bats that 'see' using their ears, and the extraordinary tarsier with its moonlight-catching eyes. Children also discover the tanuki - a real Japanese night animal with centuries of folklore behind it - and learn why almost all of Australia's native animals wait for dark before venturing out. This preschool podcast keeps ages 2–4 active with a gentle quiz, three fast fun facts (including why cats' eyes glow), and a road challenge where children close their eyes and listen for sounds around them - perfect screen-free quiet time on any drive. As a toddler podcast designed for the car, every segment is paced for short attention spans without ever feeling rushed. What You'll Discover:• Nocturnal means awake at night - and some animals sleep all day so they can work while we dream• Owls have feathers so soft their wings make no sound at all when they fly• Bats shout and listen to the echo to find food in the dark - they see with their ears• A tarsier's eyes are each bigger than its own brain, which helps it catch moonlight the way a big bucket catches rain• Fireflies light up their bottoms to find friends, and cats have a tiny mirror inside their eyes that makes them glow in the dark The nighttime setting is handled with warmth throughout - Nova frames darkness as simply where nocturnal animals belong, describing it as 'just home,' so there is nothing frightening here for a 2–4 year old. The road challenge asks little ones to close their eyes and find three different sounds around them - which makes the car itself part of the episode.

   Australian Animals: Kangaroos, Koalas & Platypus

   In this episode of The Brain Bus: Tiny Explorers, your 2-to-4-year-old discovers that a newborn kangaroo is no bigger than a jellybean - and climbs into its mother's pouch all by itself. This 10-to-15-minute episode is sized just right for little listeners in the back seat. Nova guides young Explorers across Australia to meet four remarkable animals: the kangaroo (and its jellybean-sized joey), the egg-laying platypus, the 20-hours-a-day-sleeping koala, and the laughing kookaburra. Kids hear a retelling of an Aboriginal Australian story about how the kangaroo's pouch came to be, answer three simple quiz questions, and join a seated road challenge where they bounce like kangaroos and imagine what they would carry in their own pouch. This toddler podcast keeps children actively engaged throughout the drive - no screen needed. Whether you're after a screen-free quiet time activity or a preschool podcast that holds a two-year-old's attention, this episode delivers real facts in language tiny listeners actually understand. What You'll Discover:• A newborn kangaroo is about the size of a jellybean and has no fur or open eyes when it is born• The platypus has fur like a puppy but a beak like a duck and lays eggs• Koalas sleep around twenty hours every day because gum leaves give them very little energy• The kookaburra makes a sound that resembles loud, rolling laughter - used to call out to family and claim territory• Wombats produce cube-shaped droppings, and kangaroos can only move forward - they cannot walk backwards All content is gentle and age-appropriate for 2-to-4-year-olds - the Aboriginal storytelling segment is introduced with gratitude and framed as a beautiful gift story, with no scary or upsetting elements, making this episode safe for unsupervised car listening. The seated kangaroo bounce in the Road Challenge segment gives backseat passengers something physical to do mid-drive - little shoulders will be boinging the whole way down the highway.

This 10-minute listen is gentle enough for screen-free quiet time in the car and warm enough to spark real conversation on the way. Nova guides little ones through the deep blue with calm curiosity and zero overwhelm. Little explorers dive into the ocean alongside Nova to meet blue whales and dolphins - finding out why whales must swim to the surface to breathe, just like we do in the bath. Children join a breathing exercise where they blow air out like a whale's spout, hear a retelling of the Māori story of Paikea riding a whale to shore, and take a simple true-or-false quiz about what they've learned. This episode is a wonderful screen-free quiet time option for long drives - ideal as a toddler podcast or preschool podcast that holds a 2 to 4 year old's attention through story, sound, and gentle participation. What You'll Discover:• The blue whale is the biggest animal ever - as long as three buses lined up, with a heart the size of a small car• Whales breathe air through a blowhole on top of their head, and are not fish• Every dolphin has its own unique whistle sound that works like a name• Narwhals are real whales with a long spiralling horn, living in the actual ocean• The Māori people of Aotearoa have a traditional story about an ancestor named Paikea who was carried to shore on a whale's back All content is calm and age-appropriate - the ocean and its creatures are presented as wondrous rather than scary, the Māori story of Paikea is told with warmth and respect, and there are no startling sounds or stressful moments, making this a comfortable listen for toddlers without parent supervision in the car.

    Sharks: Glow, Teeth & Why They're Actually Shy

    This episode of The Brain Bus: Tiny Explorers gently reframes sharks, not as monsters, but as shy ocean animals with remarkable tools like bioluminescence, thousands of replacement teeth, and bodies made entirely of cartilage. Designed for ages 2–4 and running around 15 minutes, it gives little ones real facts delivered at a pace they can actually absorb. Your child swims alongside Nova into the deep blue ocean to discover that sharks were already swimming before dinosaurs walked the earth and that some sharks are small enough to fit in a toddler's palm. As a screen-free quiet time activity perfect for car rides, this episode guides tiny listeners through interactive moments like holding out their hands to imagine a dwarf lanternshark, wiggling their fingers like fish, and touching the tip of their nose to feel what a shark's body is made of. A retelling of the Fijian story of Dakuwaqa, a great shark who promised to protect island people, introduces children to a culture where sharks are guardians, not threats. This preschool podcast episode wraps with a gentle reflection: sharks haven't needed to change in millions of years, because they were already perfectly made. What You'll Discover:• Sharks are shy - most swim away from people rather than toward them• Some sharks glow in the deep dark ocean, including the tiny dwarf lanternshark which is small enough to fit in a child's hand• Sharks have no bones, their whole body is made of cartilage, the same bendy material at the tip of your nose• Sharks grew new teeth their entire lives, with thousands replacing each other in a continuous cycle• In Fijian tradition, the great shark Dakuwaqa is a protector of island people, not a danger Sharks are presented throughout as shy, fascinating animals, any potentially startling ideas (darkness, size, teeth) are immediately reframed with warmth and wonder, making this episode easy listening without supervision. The road challenge invites kids to open and close their mouths like a shark breathing and wiggle their fingers like passing fish, a perfectly contained, seat-friendly activity for the back seat.

This 15-minute episode is built for little listeners in the car, with gentle pacing and warm, curious delivery from host Nova. Nova guides Tiny Explorers through each of the five senses eyes, ears, nose, tongue, and skin revealing one surprising fact about each. Children learn that their nose can detect more than one trillion different smells, that their ears never stop listening even during sleep, and that taste and smell work as a team (which is why food seems flavourless when a cold blocks the nose). With a built-in Sense Detective road challenge, this preschool podcast turns the car window into a hands-on sensory experiment, no screen required. It works beautifully as screen-free quiet time while still giving little brains something real to chew on. What You'll Discover:• Your eyes see everything upside-down and your brain flips the image right-side-up• Your ears keep listening even while you are asleep• Your nose can tell apart more than one trillion different smells• Taste and smell work together, a blocked nose makes food taste like almost nothing• Your skin is your biggest sense and fingertips can feel a bump smaller than a grain of sand All content is gentle, age-appropriate, and framed warmly, there are no startling topics, and the episode closes with a quiet, reassuring reflection that is perfectly suited to unsupervised car listening. The Sense Detective challenge invites little ones to close their eyes and notice what they can hear, smell, and feel right there in the car, so the road trip itself becomes the activity.

    Echolocation & Animal Superpowers for Tiny Explorers

    In this episode of The Brain Bus: Tiny Explorers, children aged 2–4 discover that bats have been using sound to navigate in complete darkness for 52 million years, longer than most mountains have existed. Nova walks little ones through echolocation, dolphin clicking, and the platypus's bill that feels tiny electrical zaps from bugs in the mud. The episode runs approximately 15 minutes and is gentle enough for independent listening on a long drive. Your child joins Nova on a journey through the night sky with bats, underwater with dolphins, and into an Australian creek with a platypus, all without a screen in sight. This episode is designed as screen-free quiet time that holds toddler attention through story, sound effects, and a hands-on tongue-click challenge your child can try right in the car seat. As a natural fit for a toddler podcast or preschool podcast, it layers real animal science into short, warm storytelling moments that 2–4 year olds can genuinely follow. Children also meet a shark that feels heartbeats through tiny holes on its nose framed with care so the science feels wondrous rather than frightening. What You'll Discover:• Bats shout high-pitched squeaks and listen for the echo to find insects in the dark, a skill called echolocation• Dolphins have a squishy blob called a melon on their foreheads that focuses clicking sounds to locate fish underwater• A platypus swims with its eyes closed and uses its flat bill to detect tiny electrical signals from bugs moving in the mud• Sharks have small holes on their nose that can sense the electrical zap of another animal's heartbeat• Some moths can hear a bat's echolocation call coming and dive to escape, the prey has superpowers too All animals including sharks are introduced with curiosity and warmth rather than fear, and the episode is fully appropriate for unsupervised car listening with toddlers and preschoolers. The road challenge invites your child to click their tongue and listen for the tiny echo bouncing around inside your car a genuinely fun moment to try at a red light.

    Volcanoes: Fire Mountains for Tiny Explorers

    In this episode of The Brain Bus: Tiny Explorers, children aged 2–4 discover what a volcano actually is. From the hot melted rock hiding underground all the way to the moment lava cools into a new island. Nova explains magma, lava, and how volcanic islands form using comparisons your toddler already knows: melting ice cream, squeezing toothpaste, and honey dripping off a spoon. Each episode runs around 15 minutes. Short enough for a suburb hop, long enough for the highway. Your child will travel with Nova to a 'mountain that sneezes hot, melty rock' - learning the words magma and lava, and understanding why volcanoes erupt through gentle, playful analogies. A respectfully told story from the Native Hawaiian tradition introduces the volcano goddess Pele and explains how Kīlauea has been building the Hawaiian islands for generations. This toddler podcast episode also includes a breathing road challenge where little ones pretend to be erupting volcanoes, making it a natural fit for screen-free quiet time on long drives. Designed as a podcast for 2 year olds and up, the pacing is unhurried, with built-in pauses for tiny voices to call out answers. What You'll Discover:• The ground beneath us has a hard outer shell, and underneath it the rock gets so hot it melts into a runny liquid called magma• When magma pushes up through a volcano and bursts out the top, it is called lava and lava glows orange and yellow like fire• Lava flows slowly, cools into solid black rock, and that is how new land including islands in the ocean is created• The Native Hawaiian people have a story about Pele, the goddess of volcanoes, who made her home inside Kīlauea and is said to be building new land with every eruption• Some black sand beaches are made from lava that cooled into tiny grains over thousands of years Volcanoes are introduced as a natural, non-threatening part of how the Earth works and Nova explicitly reassures listeners that volcanoes are 'just doing what they have to do,' and the episode closes with a calming reflection rather than anything alarming, making it comfortable for unsupervised car listening. The breathing road challenge, where kids fill their tummy like a volcano and slowly 'erupt' with a big whoosh, gives little passengers something to do with their hands and breath while you keep your eyes on the road.

    Dinosaurs for Toddlers: T. Rex Teeth, Arms & Big Chomps

    Your toddler is about to find out that baby T. Rex was covered in soft fluff - and that a chicken is T. Rex's closest living relative. This episode of The Brain Bus: Tiny Explorers is built for ages 2-4, running around 11 minutes, and designed to hold little attention spans from first stomp to final chomp. Nova takes toddlers on an ears-only journey back 66 million years to meet T. Rex - discovering banana-sized teeth, arms too short to reach its own nose, and a mouth so powerful it could crunch through bone. This toddler podcast uses simple comparisons children can feel in their own bodies: two legs just like theirs, arms tinier than theirs, and a head as big as a whole grown-up lying flat. Little ones join a movement challenge, answer true-or-false questions out loud, and hear the reassuring fact that every T. Rex is long gone - we only know about them because scientists found bones buried deep in the ground. A genuinely useful preschool podcast for screen-free quiet time on any drive. What You'll Discover:• T. Rex had more than fifty teeth, each as long as a banana, and grew new ones whenever old ones fell out• T. Rex's arms were smaller than a toddler's arms and could not reach its own mouth• Baby T. Rex was likely covered in soft fuzz, similar to a baby bird• Birds - including chickens are T. Rex's closest living relatives today• Scientists learn about T. Rex by finding bones that turned to rock over millions of years, including a famous skeleton called Sue The episode acknowledges that T. Rex was a predator in plain, age-appropriate language, and explicitly reassures toddlers that all T. Rexes are gone and that they are safe on the Bus, no scary imagery, no jump scares, and any intense sound effects are immediately followed by Nova's warm, steady voice. When Nova cues the T. Rex arm challenge - elbows tucked in, hands wiggling - watch every passenger in the back seat try (and fail) to scratch their own nose.
