Jelly red pandas in a Three.js soft-body simulation

The full story

Starting from a copy of someone else's blue-whale jelly artifact, a three.js soft-body simulation, the maker gave Fable 5.2 a one-line prompt to make red-panda jellies. Three of them now wander a table: they hop and bump into each other, stand up and rawr when startled or picked up, wriggle upright when flipped, and eat berries that glow in their tummies when the lights go out.

Each panda is about 470 particles and 1,200 tetrahedra solved with XPBD at 60 Hz, with the jelly look from the original's hand-written refraction shaders. Claude added the panda shape, three bodies in one solver, the hopping and standing, and the berries. Testing the physics headless first, it found the original simulation quietly drained spin from rotating bodies, which was why a flipped panda couldn't roll back, and fixed it.

It is a remix, not from scratch, and the demo GIF was staged for the camera.
