A woodchuck can traverse water, and dig straight through solid rock. It has an animal body. It has no hands.

The Usenet Oracle requires an answer to this question! > How much wood could a woodchuck chuck if a woodchuck could > chuck wood? "Oh, heck! I'll handle this one!" The Oracle spun the terminal back toward himself, unlocked the ZOT-guard lock, and slid the glass guard away from the ZOT key. "Ummmm...could you turn around for a minute? ZOTs are too graphic for the uninitiated. Even I get a little squeamish sometimes..." The neophyte turned around, and heard the Oracle slam his finger on a computer key, followed by a loud ZZZZOTTTTT and the smell of ozone.
