The Gup-E is a Gup with two areas for the Octonauts to go in and it is Peso's favorite. Peso uses the other area for the sick creatures he helps. He can also transform it from a normal Gup to an emergency Gup with a siren. It is made to look like a guppy, a baby fish. In between the front and back, there is also a lime colored door, like the paint with the rest. The top(but not touching the ceiling) has a porthole.
