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. His figure resembles SpongeBob but he has a slightly different outfit including a 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 heard the story of Great Patty Caper. He told his grandfather SpongeBob, "Shh! I just beat my high score!" Like SpongeBob in the past, he is voiced by Tom Kenny. It is unknown if he lives in 124 Conch Street as shown at the end of "The Great Patty Caper" inside of a pineapple. He is interested in video games and beating high scores and not so interested in his grandfather's past adventures. Since SpongeBob has a grandson in the future that might suggest he got married and had kids.
"Shh! I just beat my high score! Oh Yeah!" (first line)
"We paid ten dollars for this?"
