Referee Teemo or Dunkmaster Teemo
Need I say more?
Basketball skinned mushrooms. The sound of a ball popping Whzzzzzzzzzzz
A referee whistle for a blowgun, or maybe just don't reskin it at all
Jersey like Darius if he is a Dunkmaster. Otherwise white/black referee is fine.
Too many Teemo skins? I say not enough.
On a side note: even though he's been rebuffed recently, he still plays like garbage. Gotta drop that arm timer to make him viable in group fights.
