*Baxter Stockman is the creator of the "Mobile Offensive Underground Secret Excavation and Retrieval Sentries" called Mousers. These highly intelligent robots are programmed by Stockman to search for items around the city and steal what is valuable. They are trained to defend themselves by using their strong jaws to chew through anything that comes their way. The Turtles have their hands full with these little fiends roaming the city! *Source: playmatestoys.com
