Joehio is the Petorian name for the land that encompasses Joe Swanson's backyard. In "E. Peterbus Unum", Peter Griffin annexes it. After the United States government hears about this, they take this as an invasion and has Petoria put under siege. After the ensuing Operation Desert Clam, the name was dropped and the land was returned to Joe. In a recent return to the land, an unofficial scuffle between their infant children, Susie Swanson and Stewie Griffin, occurred, with the Swanson side victorious once again.
