Mousers

The Mousers are a type of robot created by Dr. Baxter Stockman. The robots are about knee high. They have a head with sharp teeth and two legs. Their jaws are strong enough to bite through steel.

Dr. Stockman created the Mousers under the premise of selling them to the government to fight New York City's rodent problem. However, his true intent was to use them to tunnel into bank vaults to steal valuables.
