SpongeBob's grandson[1] is a character who appears in the episode "The Great Patty Caper," where he is shown 75 years into the future. While the episode does not reveal his relationship to SpongeBob, it is confirmed in the credits.


He strongly resembles SpongeBob, but he has a slightly different outfit, including a red cap. However, he does not wear a belt and also wears a red tie that is similar to a "Kentucky bow tie" on his pants.


He was born to a son or daughter of SpongeBob and his or her spouse.

Role in episode

SpongeBob's grandson appears at the end of the episode, where he is being told the story of where SpongeBob and Patrick went on a quest to find the Krabby Patty formula (see the episode for more information). However, he is not interested in this story and cares more about playing his video game.


Relationship with SpongeBob

Their relationship is grandfather and grandson. SpongeBob's grandson does not seem to be interested in what happened in SpongeBob's youth, as seen when he ignored his story. However, SpongeBob is not fazed by this treatment and is amused by his grandson's behavior.


  • This character shows that SpongeBob will eventually have at least one child, who has a son.
  • In the episode "Pineapple Invasion," SpongeBob's grandson is indirectly referenced when SpongeBob mentions that he was going to give the bronzed version of his first Krabby Patty to his grandchildren.
  • His outfit resembles that of his ninth great grandfather SpongeBuck SquarePants.
  • If SpongeBob has a daughter and not a son, then his grandson is another family descendant.
