It is a two man submarine with rudders near the entrance and two other rudders near the back .The exterior of the submarine is made mostly of orange and white to match Stampy's skin. The submarine is also meant to look like a clown fish. The interior features a control panel where Stampy can steer the submarine. At the back is a small room where Stampy and his friends can relax in.
Stampy first began to build it in Episode 164 (dubbed submarine). He finished it between videos and first used it in Episode 165 (dubbed ocean adventure).
