Wobbuffet Heartless

I kind of thought it was inevitable. 'Scuse the lighting, I didn't take it too seriously.
Now that I think of it, the design reminds me more of a Nobody, but never mind because it has a Heartless symbol.
Besides that, Wobbuffet are supposed to live in a dark cave, right? Darkness. Yeah.
This Heartless can be damaged only by attacking its tail.
