The Mousers v2.0 are, as mentioned, more advanced versions of the original Mousers. Just like them, they have a metal shell and a powerful bite that can bite through steel easily, but they are in some ways significantly different: * They have four legs, a pyramid-like arrangement of three eyes, and a long-drawn-back head; * They reach a length of about 8 feet (about 2.40 meters); * Their metal shell is much more resistant to physical damage, even against small arms and weapons of the Turtles; * For better transport these Mouser can be rolled into balls.
