As is, the sky parts of World 8 (i.e. World 8-3 and the end of World 8-2) in the Super Mario Bros. 3 Skin clash horribly in tone with the rest of World 8. I have a suggestion that changes not only how it looks, but also how the World 8-4 Castle looks as well. In Super Mario Advance 4, the last two e-Reader levels take place on an Airship, and parts of them actually take place inside them, not just for the boss battle. What I'm saying is that the Lost Levels World 8 could be about an airship raid when playing with the SMB3 skin.
