Planktopolis is the temporary rename of Bikini Bottom when Plankton succeeds in bringing about Plan Z and enslaves all the Bikini Bottomites, using mind control bucket helmets. It is seen in the The SpongeBob SquarePants Movie and the video game.


Planktopolis looks very gloomy and the sky is a gloomy dark red color. Planktopolis is filled with Plankton statues which Plankton's mind controlled slaves built for him. In the background of Planktopolis, the Krusty Krab can be seen as well as the Krusty Krab 2. There are also three statues of Plankton that can be seen around the town. The mind-controlled Bikini Bottom citizens can also be seen working for the evil Plankton.
