I've got the proof of intelligent design, but what or whom was it made for?

Found on a beach and kept in this case, the proof exhibits sophisticated use of tools (waves, abrasive surfaces), and nipples.

It is cleverly constructed from a sea urchin's exoskeleton, though whether the urchin was struck dead to furnish the art material or whether this is recycling of trash, is something that others might debate.

This object couldn't randomly be produced.
