Command Module
The Command Module is a device that Plankton made to impress Karen. The hairdryer on it has a built-in flamethrower. The Module has only been seen in the episode "Komputer Overload." The Module disliked other robots and attempted to demolish them, but later, the robots combines into one robotic mayhem machine for Plankton to control, with the Module in the top section. At the end, since the giant robot is connected to a plug and came closer to the Krusty Krab, the plug came off, thus, the robot toppled and fell, leaving Command Module and the others destroyed, ending Plankton's plan to steal the formula.
Looks
The Command Module is an old hairdrier taped to the back of a miniature windmill.
