Ahhhh, I can't tell you how glad I am to finally get rid of that ugly question mark in my sig
Looks like a Grass-type Aipom... huh. Looks leaner than his toy made him appear. (Personally, I think the toy was cuter...)
So... Yanappu, eh? Guess its not Burokko. Should the name be romanized as Yanap, as Perappu -> Perap?
Acrobat clearly is a move that can hit Pokemon in the back during a rotation battle. I'd guess Normal type.
And they say someone owns this Pokemon... gotta be Dento.
The romanization takes the "Yana" as willow and the "appu" as ape.
So, basically, Willowape.
