Vaporeon is a Pokémon that shares physical traits with both aquatic and land animals. Vaporeon's body is light blue with a dark blue marking around its head and a spiky ridge down its spine. It has black eyes and a tiny black nose. There is a white fin encircling its neck and three fins with cream-colored webbing on its head. Two of these fins are on either side of its head, similar to ears; and one is directly on top of its head, resembling a dorsal fin. Vaporeon is a quadruped with three small toes on each foot and dark blue paw pads on the hind feet. Its split tail fin has been mistaken for a mermaid's in the past and is believed to be the origin of mermaid folklore. It can detect moisture with its fins, which vibrate when sensing incoming rain
