Crap! Poison Gas was the one move I could think of that I practically never see. Which makes sense, given Toxic renders it moot and has been around for just as long.
As for Garbodor, it's sorta cute in an ugly way... like bulldogs and pugs. I don't like the mickey mouse ears on it though. It is amusing that the GARBAGE pokemon actively works to clean up the earth and cut down on trash, though. It even learns Recycle! Trubbish is cuter though.
