Ok, this has been bugging me for a while. I keep seeing this one screenshot of Mario Advance 4 that shows Racoon Mario in a level that seems to be made out of music note blocks. The thing is, he's fighting a couple of Mario World type Goombas. I would assume it's an E-Level.
Can anybody tell me if those types of Goombas are actualy in the game? Just out of curiosity.
