Okay, I have to admit, Krazy Krumb Land is pretty funny.
Maybe a good idea would be a desert world? They had one in DK 64, but never for a DKC, have they? It should be called... Dusty Desert Danger A boss level could be Sandstorm Show-Down. The boss should be King Kobra.
I really want to see a savanna-like world. With acacias and baobabs and mountains and perhaps sunsets too. That'd be swell! Mostly because DKCReturns at some parts, really give me an African vibe.
