The dinosaur who lost his colors
A kids' cartoon for YouTube Shorts: Bobo, a tiny mint-green baby dinosaur, wakes up to find all his colors have gone grey. He asks his jungle friends for help and gets a splash of color from each one. Ends rainbow-bright and giggling. Gentle, cheerful narration for 3–6 year olds.
Use this idea →Learn colors with a bunny
Learn colors with Lulu the bunny! A cute white bunny hops through a magical garden finding a red strawberry, an orange carrot, a yellow sunflower, a green leaf, a blue puddle and a purple butterfly. Say each color clearly and happily so toddlers can repeat along.
Use this idea →A little lesson about sharing
A short kids' story about sharing: Benny the baby bear finds a pot of honey and wants it all for himself, until he sees his friends are hungry. He shares, and they have a picnic together. Warm narration that ends with 'Sharing makes everything sweeter.'
Use this idea →Bedtime story
A calm bedtime story for toddlers: a sleepy little moon can't fall asleep, so the stars sing it a lullaby one by one until it yawns and closes its eyes. Soft, slow, soothing narration and dreamy colors.
Use this idea →Counting to five
Count to five with five little ducklings: one by one they waddle down to the pond and splash in. Count each one out loud slowly and happily — one, two, three, four, five — for preschoolers.
Use this idea →How to make a kids' cartoon with Slice
- Write the story in a sentence or two. Who's the hero, what goes wrong, how it ends happily. "A baby penguin is scared to swim, his grandma helps, he turns out to be the fastest swimmer" is plenty.
- Pick Pixar as the style for the classic 3D cartoon look, or Claymation or Watercolor for something gentler.
- Choose a length. 20–45 seconds suits YouTube Shorts and young attention spans.
- Tap Generate. Slice writes the narration, animates every scene, adds a friendly voice, big captions and music.
- Change anything you like — a scene, a line, the music — then download it or post it.
Tips for cartoons kids rewatch
- One simple story. A problem, a helper, a happy ending. Kids follow one idea, not three.
- Give your hero a name and keep them. Create them once under Characters and they look the same in every video — that's how a channel becomes a show kids ask for.
- Teach one thing. Colors, counting, sharing, being brave. Say it out loud so little ones can repeat it.
- Write in their language. Type your idea in Spanish, Portuguese, French or any language and the narrator speaks it.
- Make it a series. "Bobo's Adventures, Episode 2" keeps viewers coming back — see making a series.
Posting to YouTube? When you upload a cartoon made for children, YouTube asks you to mark it as made for kids — that's required for children's content, and it's a setting on YouTube's side.
Questions
Can I make cartoons for my kids' YouTube channel with Slice?
Yes. Describe the story in a sentence or two and Slice writes it, animates every scene in a 3D cartoon style, adds a narrator, captions and music, and gives you a vertical video ready for YouTube Shorts, TikTok or Reels. The videos are yours to post anywhere.
How do I keep the same character in every video?
Create a character once under Characters — for example a baby dinosaur with a name and a look — and pick it on the new-video page. Slice keeps its look the same in every scene and every episode.
Which style looks most like a kids' cartoon?
Pixar-style 3D is the closest to the cartoons kids already watch. Claymation and watercolor also work well, especially for calmer bedtime stories.
Can the narration be in another language?
Yes. Write your idea in the language you want — Spanish, French, Portuguese, Hindi and many more — and Slice narrates in that language.
How long can a cartoon be?
Up to 90 seconds. The free trial makes videos up to 15 seconds; credit packs unlock longer ones. Most Shorts work best at 20–45 seconds.
