The Wrist LoJack-a-mater is a device that Leela wears on her right wrist. The Wrist LoJack-a-mater can easily be used in many ways like using a face laser to attach a body part to a living thing, help tracking down Bender's brain, is able to determine whether someone is edible or not (when Leela discovers Popplers) and even have some video games, like Tetris, on it. During the Fon Fon Rubok of Amy and Kiff, Leela was seen playing Pong behind a tree. When the robots rebelled against Humans in Mother's Day, Leela's LoJack-a-mater jumped off and suggested Leela "Wash her wrist once in a while".
