sylveon is a fairy type Pokémon that gets shipped with every Pokémon ever and more. Sylveon is most often shipped with umbreon to the point when you google sylveon you will see shipping art, also, kids, turn on safe search to protect most of the cursed things you will unwillingly see and your innocence will flutter away like a butterfly would.

the internet is messed up, stop drawing porn of pink, kid friendly cartoon animals, y 'all need therapy.
