Role in series


SpongeBob gets a letter from his eponymous cousin. It says that he is out of prison and has decided to pay Harold and Margaret a visit. It also says that if SpongeBob wants to see them again, he needs to have a wrestling match at their house. SpongeBob gets nervous because when he was a kid, BlackJack would beat him up.

SpongeBob decides that he needs to save his parents, so he runs to the house. It has police tape around it and the whole house is covered with plastic. SpongeBob thinks that a crime has occurred. He forces his way in and notices that several pieces of furniture in the living room are covered in plastic. He continues walking until he notices a broken picture of him and his parents. SpongeBob imagines that his parents are having a peaceful night watching TV, when BlackJack bursts in and kidnaps them.

SpongeBob then finds a cabinet that also has plastic on it. Inside, there is a note that says BlackJack has visited Grandma SquarePants' house.

Towards the end of the episode, SpongeBob finds his parents at BlackJack's house. They are putting up decorations for a party. They reveal that the broken image was just Margaret accidentally dropping it and the house was covered in plastic because it was being fumigated for krill.

"Truth or Square"

When Mr. Krabs has a flashback to when Krabby Patties cost 10 cents, SpongeBob is shown in the living room of his parents' house, watching TV.


SpongeBob and his parents lived here by the time SpongeBob was a baby.

At some point, the rug shown in "Truth or Square" was removed from the house.
