What is Ninfia/Sylvion's type?

This is a very interesting subject and I just NEED to post about it.

So... what type IS it?

Flying?
Erm... Please compare the other pure flying types to Ninfia.

It doesn't look like a flying type ether. Apparently Syl means fly in greek, but note that that is the AMERICAN name, not the Japanese one! All this is done in Japan.

Poison?

No. No. No.
Normal????

Please tell me why it would go from brown to pink????
So... the mystery lives on... until October at least.
Please tell me YOUR opinion in the comments.
P.S. FYC? Are you going to post?
