History
Enemy In-Law
Plankton used it to bring the people to the Chum Bucket, but left angrily when Plankton captures them to be demanded to eat there. The Robot is so tough that its fist can break a huge rock in small pieces. The Robot is seen again at the end of the episode showing that he might be in love with Betsy, then he waited in the car. He also has laser eyes, which he uses to spell an "I love you." to Betsy Krabs.
SpongeBob's Atlantis SquarePantis
In the level, "Armory Antics!" and its second variation, in one of the lines that Plankton says when he gets hurt, he mentions that he wishes he brought his Chumbot.
