Where's it from: Teenage Mutant Ninja Turtles (1987)
Baxter Stockman is a proactive kind of guy. If you have a rodent problem, forget the glue traps and the poison. Get a robot with sharp metal teeth, and let it chew through the wall. Shredder recruited Stockman to create hundreds of these "Mousers." In one of the most memorable scenes from the 1987 cartoon, the Mousers break into the Turtles' underground lair and try to kill Splinter. Thankfully, his sons arrive just in time, and they turn the would-be rat killers into a pile of spare parts.
