List of characters

JK [2] is the guard worm of The Dump.


He is a large light green worm with black eyes and a unibrow. He wears a spiky gray collar.


He appears to be a friendly worm. However, when he is either awoken or believes that there is a threat to the Dump, then he became aggressive. He enjoys playing fetch.


The Lost Mattress

He first appears sleeping on Mr. Krabs' mattress. Squidward, SpongeBob, and Patrick plot to try and get the mattress from him. All of their plans fail. When Mr. Krabs is awoken by the smell of his money, he joyfully reconciles with his mattress. When JK attempts to scare off Mr. Krabs, he growls and whips the mattress, making JK go flying. JK lands in Squidward's arms, who throws him down and goes running from JK, who is chasing him down the road, trying to bite him. The Lost Mattress ends when they go off of the screen.

SpongeBob SquarePants featuring Nicktoons: Globs of Doom

His name is revealed in this game. He appears in the second level, where he is hostile, albeit not being able to fight him. Mr. Krabs' mattress, or more likely a different one, is with him.
