Real Cactus

Tap it to drop it; drag to turn it.

A round cactus, captured from photos and drawn with thousands of splats. Cactus spines are leaves that dried into needles; they shade the plant and cool it, catch dew and keep animals from eating it. The ribbed stem stores water and swells when it rains.

Tap it and the cactus in its gravel is lifted a little and set down with a bump. Drag to circle it and look at the pattern of spines.
