"The Water Suit" was a mechanisim used by Milo, Bea, and Oscar in the episode "Fish Out of Water" where the three friends use it so they can explore outside the tank. It is also seen in "Doggonit" where Milo, Oscar, Bea use it to get to the scorpion tank and Oscar's break. The water suit is a backpack-like machine that sprays steam or water into the person who is wearing it's eyes. It also has lots of water in the back of it that seems to never wear out.
