Tumbleweed

A dry tumbleweed, a roughly spherical ball 0.6 m across built from a few interlocking faceted twig fans rather than a solid blob, open enough to see through with an uneven ragged outline and a broken stem stub on one side.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
