The SPU-31

The Noxious Enterprise's Super SPU-31 Liquid-Cooled Mobile Processing Unit is a device Plankton made to impress Karen. It has a built in hammer that crushed Plankton. It is only seen in the episode: Komputer Overload. SPU-31 disliked other robots and fought them, but later, the robots join forces into one giant robot for Plankton to control, with SPU-31 in the bottom section. At the end, since the giant robot is connected to a plug, when the robot came closer to the Krusty Krab, the plug came off, thus, the robot toppled and fell, leaving SPU-31 and the others destroyed, and Plankton sobbing.
