Vaporeon

Vaporeon is a Water-type Pokémon from the Kanto region. It evolves from Eevee after being fed 25 candies.

Trivia

 * There is an easter egg that refers to the names of the Eevee Brothers. Naming Eevee to Rainer will result in a Vaporeon when it is evolved.
 * Works only once per account and even if Eevee was already evolved into Vaporeon not using this method.
