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.
