Joe Bob is a Laistrygonian giant who, along with Marrow Sucker and Skull Eater, was part of the group of giants that infiltrated Percy Jackson's school in The Sea of Monsters posing as visitors from Detroit.
Percy Jackson and the Olympians
The Sea of Monsters
While undercover, they were recruited by Percy's new bully Matt Sloan to play against him in a dodgeball game. During the game, they transformed and attempted to kill Percy. Joe Bob himself would have succeeded had Tyson and Annabeth not been around, who aided Percy in defeating Marrow Sucker and Skull Eater, as well as all the other giants. Joe Bob, who can arguably be named the most intimidating giant of the fight, was the last standing and having knocked out Percy's Cyclops friend, Tyson, was only prevented from accomplishing his mission by the timely arrival of Annabeth Chase, who, using her magical Yankees cap, snuck up behind him and disintegrated him with her knife, sending him to Tartarus, from which it is assumed that he has not yet returned.
When Tyson creates a shield for Percy, one of his designs on it is of Annabeth killing Joe Bob.
Appearance
Joe Bob is described as a typical Laistrygonian giant. He has a tattoo on his biceps that reads, "J.B. luvs Babycakes". Given his continued ranting throughout the fight, Babycakes is presumably either his girlfriend or pet, possibly a monstrous dog or a hellhound of some sort.
