That's funny. DKC2 literally is made up of same places reskinned with different colors:
Woohoo we're on a pirate ship!
Now the endless ocean background is green...
I don't get why they made the ocean background green instead of putting the swamp background behind the ship foreground. It looks like a radioactive ocean rather than a swamp.
Tropical Freeze, on the other hand, has unique visuals for every single level. And mangroves fill with wrecked ships and aircrafts and fruit juicing jungle factories aren't exactly played out.
