well, lets see, stage ideas. well picking one at random. say the jungle. first part I can see as a sort of enter the jungle sort of thing, the further you go the more jungle like the stage gets, ending with some platform jumping in tree branches. possible hazards could be monkeys appearing above you and throwing banana's at you. if you get bananaed you get turned into a monkey.

since it's a fairly late level you can make things a bit more difficult with Osaka seeking bananas or something.

I can also see a segment where you have to dodge tiger, or panther cubs or something or they turn you into there mother. and maybe a segment where you have to jump on crocodiles heads without falling in and becoming one while they duck under the water in patterns. if you could get a vine swinging mechanic working it could be fun here. also you could have fake vines that are actually snakes that do something.
