Rickety Rapids is similar to Tracker Barrel Trek in DKC3: Both are waterfall levels, and they have Tracker Barrels and many Buzzes to avoid. Both of them have Ellie as well, but in this level, Ellie is well-hidden at the beginning, and you can't use her for the entire level anyway. Not that I even use her... also, Tracker Barrels don't shoot you as high in this game, so Buzzes are hard to avoid!
