Pokemon Vaporeon! #134
Vaporeon is a composite creature sharing physical traits of aquatic and land animals. This Pokémon has a tailfin, a white ruff around its neck, and three fins around its head. It is said that rain will come within a few hours if Vaporeon's fins begin to vibrate.
(The tail is the only tail available on gaia with a fin that would not get rid of the legs, and the shark head fin is the best representation I could get of it's top head fin.)
