I've been working on custom NSMBWii textures lately, and I can't help but wonder how awesome it would be to recreate some levels and implement these custom textures. Level editing is one thing, but if manipulated correctly, object-oriented textures can alter a stage even more. On that "haunted shipwreck" video, I couldn't help but notice these guys would have been some excellent scenery boosters:
They're the Castle Goombas (gray ones). And for those underground levels, I'll make Blue Goombas later on.
