Sylveon - So that's what the ribbons are for.

Fairy type confirmed! Since Pokemon don't wear clothes, and with the exception of Cubone's helmet and a rare few others, all "accessories" are part of the Pokemon, this was the first thing I thought of when I looked at Sylveon and its ribbons. It's playing Emerald version.

lol flesh tentacle ribbon hands.

Update: The ribbons are actually prehensile feelers. This is canon. :3
