Boggy Billy is a character in The Precursor Legacy. He lives in and owns Boggy Swamp. Billy's closest companion is a hip-hog named Farthy, who fled after lurkers invaded the swamp. Billy attempted to attract Farthy back to the swamp by laying out his favorite snacks, but swarms of swamp rats continually eat them. Jak and Daxter aid Billy by fending off the rats by harnessing yellow eco. Once the rats are defeated, Farthy returns, and Billy gives Jak a power cell for his effort.
