Bulkaur

The Gluttonous Pokémon

Dragon

After consuming large amounts of critters, it gets too fat to even move. So it enters caves and disguises itself as a rock. The feather on its tail turned into a web which it uses to catch unsuspecting critters as extra meals. Reports say that Bulkaur rarely feels hunger, and the proteins of the caught bugs are used for certain evolutionary goals.
