World 3 (New Super Mario Bros.)

If you don't find the alternate exit in World 2, you'll find yourself in the tropical landscape of World 3. But don't expect to be lounging on the beach -- this world is far from paradise! This is an adaptive arrangement, meaning that what I had in mind is that the music changes as certain conditions are met, just like with World 8 in the original, vanilla New Super Mario Bros. sound gets more tropical = tower clear sax section = near castle
