Saguaro Cactus

A fluted columnar trunk with about 12 blunt ribs, a rounded crown and tiny areole spine dots; an arms knob from 0 to 5 arms that branch out and curve upward, and a height knob from 3 to 8 m with the arms placed along the height.

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
