I am so stupid. An indoor ride in adventureland...has to be the Tiki Room. (If it's not this than I definately need a clue)
That's got to be it. I checked a map online and it shows only Pirates, Tiki, and Jungle in Adventureland. I know they added Aladdin, but that's not indoors. And this mallet-like thing has feathers on it. I still can't picture where in Tiki it would be though... I've only been there once.
