Tumbleweed

Rolling tumbleweed, 0.9 m across: a dense ball of dry, wiry, branching stems in pale straw and grey-tan with no flat side, carrying a rolling-and-hopping idle animation on the kit's wind period so it tumbles about its own centre in place.

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
