Chain Chomp

A Chomp is little more than a spherical head with a vicious-looking maw attached to a long chain. It can move around without any limits if it is not attached to a stake, and even move off the ground by its sheer ferocity, but because of the likely danger a Chomp poses to almost everyone around it, they are usually encountered tied down to guard a location. Chomps appear in many Mario Games, and sometimes have variations on the original form.
