List of characters

SpongeBob's Grandson is the grandson of SpongeBob SquarePants, who only appeared in "The Great Patty Caper," where he was 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 doesn't 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 was visiting during the episode in which he appears.


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.



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.


  • "Shh! I just beat my high score! Oh yeah!" (Only Line)


  • This character shows that SpongeBob will in fact marry and had at least one kid, who in turn had at least one kid of his or her own.
  • The age of the grandson is not known. However, he cannot be older than 63 years old, assuming that Sponges (i.e. SpongeBob's child) leave home at about the age of 12 years like SpongeBob most likely did.
  • The handheld console he is playing is similar to a Game Boy.
  • This may now mean that Spongebob will probably not marry Sandy because he is all sponge.
