Skroo Gee

He is the NPC who runs the QuackQuack game at the Trool Fair. Talk to him to get the fishing rods to play the game, and talk to him again to get the reward for "catching" the false quackquack.

I swear his name is a pun on Scrooge (SkrooGee -> Skrooge -> Scrooge) from Charles Dicken's A Christmas Carol, but that may just be me.
