I want you to imagine a story. And then using threejs I want you to create full animation, Pixar-level quality 90s cartoon out of the story you imagine.
Make it yours. Write "90-second" if you mean the length, or keep "90s cartoon" for the decade's look. Put your own story after "imagine a story" if you don't want the model to invent one.
Glow-star toy cartoon in a 1990s bedroom
A 3:50 cartoon with a story Opus 5.5 imagined and animated in Three.js. The creator meant 90 seconds when writing "90s", but the model read it as the 1990s and made a period-style cartoon. It ran 7h 58m at max effort for $173.23, with no follow-ups.
“I wanted to ask for a 90 second cartoon, but I wrote it 90s so it assumed I want the cartoon from 1990s”

How it was made
Run at max effort in CRHQ, the agent harness the creator builds, with an Executor agent that has empty instructions and no skills or MCP servers. The creator wanted a 90-second cartoon but wrote "90s"; the model took it as the 1990s, and the creator let it run, which gave an almost four-minute film. No follow-up prompts. The post says to watch with sound on.

A 3D toy-world cartoon in a child's bedroom at night: glow-in-the-dark ceiling stars with faces, a small tin robot, toy blocks, a boombox and cassettes, a flashlight, and a red balloon.
- Color
- Night blues and violets lit by lime-green glow stars, a woven multicolor rug, warm wood, red accents (the balloon, the toy box, the curtains), and a soft beige close-up at the end.
- Type
- Only lettering inside the scene: MEGA BASS on the boombox, TOYS on the toy box, and letters on wooden blocks.
- Framing
- Pillarboxed, with low, toy's-eye camera angles on the floor and shallow depth of field, close-ups on faces, and one overhead view of the starry ceiling.
- Structure
- A boombox and cassettes on the floor, glow stars with faces on the ceiling, the ceiling with a planet mobile, a tin robot crossing the rug past the toy box, the robot among letter blocks with a little star, the robot with goggle eyes, a flashlight beam across the floor, a red balloon at the ceiling of stars, and a close-up of a smiling star.
