Leafeon

Leafeon is a Grass-type Pokémon from the Sinnoh region. It evolves from Eevee after being fed 25 candies if the Trainer is within range of a PokéStop with Mossy Lure Module.

Trivia

 * Naming Eevee Linnea will evolve it into a Leafeon. Works only once per account and even if Eevee was already evolved into Leafeon not using this method. When this is applied correctly, the evolve icon turns from a question mark (?) into a silhouette of Leafeon.
 * Excluding Last Resort, Leafeon is the only evolution of Eevee to have any attack (Quick Attack) that is not the same type as the Pokémon.
