A soft-body jelly buddy you can stretch, throw, walk, hop and 3D print, in three sizes. Up to four on one table, and they squish into each other.

Gummy Buddy is a free browser toy: a 7 cm soft-body jelly creature with a face that you stretch, throw, walk and hop around a table. It runs real volumetric physics (about 4,000 tetrahedra solved 240 times a second), so the wobble is simulated, not animated. No signup, no install, nothing uploaded.
Yes. Gummy Buddy is completely free, with no account, no ads inside the app, no watermarks on photos, and no locked features. Settings save in your own browser and never leave your device.
Gummy Buddy is played by hand: drag any part of the gummy to stretch it, then let go and watch it flop back. Tap or click the table to walk there; double-tap to hop. On a keyboard use W A S D or the arrow keys to walk and Space to hop. Drag the table to orbit the camera and scroll or pinch to zoom. The gear button opens flavors, wobble, bounce, gravity, mood and the table surface.
Yes. Open the settings card and tap Add a buddy. Up to four gummies share the table, each with its own flavor, and they collide, squish, stick briefly and bounce off each other. Tap a gummy to make it the one your keys and taps control.
No. Everything runs locally in your browser using JavaScript and WebGL. Nothing is uploaded, there are no servers behind it, and the only tracking is basic anonymous page analytics. Photos and STL files download straight to your device.
Yes. Print this pose exports a binary STL of every gummy on the table in the exact stretched or squashed shape on screen, about 70 mm tall at Normal size and 52 or 92 mm at Small or Big. The mesh is one closed surface with a flat bottom, so it slices in Bambu Studio, PrusaSlicer or Cura without repair. Translucent PETG or TPU gets closest to the jelly look.
Any modern browser with WebGL 2: Chrome, Edge, Firefox or Safari on desktop, iPhone and iPad, or Android. Phones run a lighter mesh automatically.
Slime and squishy apps on the App Store and Google Play are flat 2D smears with ads between every squeeze. Gummy Buddy is a true 3D soft body with volume preservation, a face that reacts to being grabbed, real bounce and friction, and it costs nothing. The idea was inspired by Scott Sun's Jelly Baby; the simulation, creature and everything else here were written for Gummy Buddy.
