Savanah level that was really wide and the sun was setting.Ice level with the ice skate and the gimmick where you had to blow into the mic to make the platform rise.Poison level with the platform that you stayed on that automatically moved and there were a bunch of phirana plants.Ninja castle.Beach level with football players.Cherry powerup stage with the platforms that switch on a timer with the bgm.Fabric level where Rosalina is unlocked and there are holes everywhere.First stage is just a generic field stage, second is an underground stage.One of the Bowser stages was a procession of tanks similar to smb3.There was a stage where you rode Dorrey. Mario Kart level.The final challenge was cool but hard to describe besides it was in space and there was an obnoxious part with a kamek.Captain Toad levels were fun too, especially the ghost house one.Sorry it's been over ten years since I played it, but those are the ones that come to mind. What a fun an memorable game, I should give it another play.
I was thinking I wanted to replay it too, or even 3D Land. But I have a list of other games I need to finish and games I haven't played that I want to get around to first.
