Plankton settles in the Dullsville Senior Living center and SpongeBob and Mr. Krabs find out that the Plankton they are following is a decoy robot. It also turns that Mr. Krabs anticipated this and sent robot copies of him and SpongeBob. With nothing more to do, the robots enjoy their time in the city until they explode on a billboard.
It is 82 kilometers (50.9524 miles) away from the Krusty Krab, according to the time card in the episode.
