Use this 3D model in my game.

Model:  Octopus
Page:   https://antics.gg/m/octopus-54539e
Asset:  https://antics.gg/m/octopus-54539e/model.glb   (CC-BY-4.0)
Recipe: https://antics.gg/m/octopus-54539e/recipe.mjs  (MIT — edit the numbers to change the model)

It has 18,707 triangles and 3 named parts, including: body, eyes, suckers.
Named parts are separate nodes, so you can move or hide them individually.

Load it at runtime — do not rebuild the geometry on the page:
  npx modelkit vendor .        # from antics-modelkit, puts glbload.js + three next to your page
  import { loadGLB } from "./glbload.js";
  const parts = await loadGLB("./model.glb");   // [{ name, geometry, material }]
  for (const p of parts) scene.add(new THREE.Mesh(p.geometry, p.material));

To change its proportions instead of using it as-is, download the recipe, run
`npm i antics-modelkit three`, edit the arguments and `npx modelkit build`.
