The Sea of Monsters What does Tyson give Percy that he's made, and what can it do? Asked by MHood2 12 years ago 8/25/2013 8:21 AM Last updated by anonymous 12 years ago 8/26/2013 2:48 PM
In The Sea of Monsters, Tyson creates a ring for Percy that turns into a shield when activated. With it, Percy is able to win the Chariot races at the end of the book. It also protects him from attack later on.
