Rise of Sqeegee 5Edit
Plankton was plotting to rule the world, and he wanted to use Sqeegee as a catalyst, so he used his revival tube to regenerate Sqeegee's body and revive him at full power. He got squashed by Sqeegee though. Later, he made Robo Sqeegee , which just blew up, and then he made Robot Sqeegee that failed because it was destroyed by the King. Plankton was eventually killed by Sqeegee's stare.
