Little Tokkers cosplaying as Cyprien from Evil Twin
Although from the looks of it the little guy hasn't quite got the character right; for starters i think Cyprien has grown out of sucking a pacifier, something which the little cub cant bare to be without XD. Also he doesn't seem to have grasped the skill of being evil and seems a little bit shy and embarrassed.
It might have also helped if he'd actually played the game before deciding to cosplay it :-P
