Umbreon is the Moonlight Pokémon. Espeon is the Sun Pokémon. Dey gawt dem awesome paper hats, bro.
Accrdifying to Bulbapedia, Umbreon has the power to emit some kinda poison similar to the one your mom makes, but the only poison type move it know is Toxic through TM, and try to tell me a non-Magikarp/Unown pkemon that can't.
Espeon is purple.
