A Plumber Ship is a spaceship Plumbers use to fly and patrol space.
According to Kevin, the Plumber Ships are quite slow and have weak engines and security.
AppearanceIn Alien Force/Ultimate Alien, Plumber Ships are circular in shape and primarily white. They has grey lines coming from the sides of them, connected to white wings. An intergalactic peace symbol is placed in the middle of the ship. The cockpit looks like the Omnitrix symbol.
In Omniverse, the sides of Plumber Ships are longer and the cockpit is more triangular. They also become mostly white with black and green parts and the Plumber symbol on the sides. The Rooters have a black and red variant.
