Wolf's costume is a sackperson
Not the dude from "9"
You can see it, right?
He even has a button that says "I ♥ Little Big Planet" so it's totally obvious!
We haven't even seen "9," Hadn't even heard of it in fact, until people kept saying that they thought that was what Wolf's costume was from
(although now we've gone and watched a preview and decided to put it on our netflix queue...)
But he is a sackperson. And don't you forget it!!
