Dewpider

Dewpider, the Water Bubble Pokémon. A Water and Bug type. Dewpider can only breath oxygen dissolved in water. The bubble serves as a means of protection to Dewpider's soft head and allows it to breathe when on land. When this Pokémon comes across enemies or potential prey, it slams its bubble-covered head into them. When meeting another of its kind, the bubbles are compared and the one with the smaller bubble gets out of the other's way.
