List of characters

SpongeBob's Grandson[1] is a character who only appears in the episode "The Great Patty Caper," where he is shown seventy-five years into the future. While the episode does not reveal the relationship of the character, the relationship is confirmed in the credits.


His figure resembles SpongeBob, but he has a slightly different outfit, including a red cap. He does not wear a belt. He 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.

He either lives at his grandfather's house or is visiting during the episode in which he appears.


The Great Patty Caper

SpongeBob's grandson appears only 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 formula (see the episode for more information). However, he is not interested in this story and cares more for his video game.

Pineapple Invasion

SpongeBob's grandson was indirectly referenced when SpongeBob mentions that he was going to give the bronzed version of SpongeBob's First Krabby Patty to his grandchildren.


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.



  • This character shows that SpongeBob will have at least one child, who has a son.
  • The handheld console he is playing is similar to a Game Boy.
