Hop's Garage is a certified used part and repairs shop in a small city north of Lucien called Skyway. It is run by a incredibly fat and blue rabbit named Hop. He does not accept customers without shirts or shoes. Hop's Garage also oils machines, according to a sign hanging on a wall in the background.
