Prompt

Make "Plush Watermelon" (Material Studies No. 032) on the Plush Penguin WebGPU engine: XPBD soft-body lattice, shell fur, cloth limbs, posture-driven gait, Hand / Finger / Comb tools.

Shape (one SDF):
- A fat wedge cut from a sphere by two planes through one horizontal axis, about 76° apart.
- The axis is the top edge, so each cut face is a semicircle.
- The cut faces are slightly puffy and every seam is rounded.
- It sits on a small flat patch of its round rind.

Regions:
- Flesh: long fluffy red minky.
- Rind: a white band along the outer edge of both faces.
- Skin: green, with dark jagged stripes running pole to pole around the wedge's axis.
- Seeds: short-pile felt teardrops pointing in toward the axis, a few on the front face around the face, more on the back.

Front face: two bead eyes, rosy cheeks, and an embroidered smile thread laid into a short-pile groove.

Limbs: two brown felt legs stuck out in front, and two stubby felt cloth arms at the wedge's ends.

Actions:
- Toddle: walk on the legs.
- Rock: seesaw forward and back on the rind with a synthesized giggle.
- Wave: arm waves and hops with a toy squeak.
- Topple: fall onto its back, then get back up.
- A finger boop on the face makes it giggle and rock; it also rocks now and then when idle.

Palettes: Classic, Yellow, Sorbet.
Readouts: mass, volume, steps, rocks.
Responsive layout with no horizontal overflow on phones.
