List of Percy Jackson and the Olympians characters
Tantalus: Tantalus is a spirit from the Fields of Punishment who becomes the activities director at Camp Half-Blood after Chiron is fired. He appears in The Sea of Monsters as a minor character. He is shown to hate Percy and his friends even more than he hates most half-bloods, yet shows favoritism to Clarisse, such as naming her hero when the camp was attacked by Cholcis bulls, or when she wins the chariot race, he throws a banquet in her honor. When the camp is attacked by a large flock of Stymphalian birds, Tantalus blames it on Percy, Annabeth, and Tyson's "bad chariot driving", despite that they were the ones who defeated the birds. When Tyson is brought to camp, Tantalus insults and makes fun of him, even when Tyson is claimed by Poseidon. He is cursed so that he cannot eat or drink, and this is made a joke when at the end of the book his curse is lifted just before he is sent back to the underworld, though none of the campers were sad to see him go.
