See how big his nostrils are? He has a fierce sense of smell. Just don't be around him when he sneezes.

He looks like he is dancing. Stomp, stomp, stomp goes his feet in time to the clicking of his clawed castanets. This attracts his prey to him. The beat is irresistible; a shave and a haircut. . .  It turns out those are not claws, they are mouths. He eats through them. There is no mouth where his mustache is.

So his teeth click as castanets.
