I don't know yet, but I did find out the river rapid game is still in the Master System/Game Gear versions, only it's a bit different: Dizzy's barrel moves a lot faster, and the trolls no longer attack from the water or the land. Instead their barrels float across certain points of the river on balloons to bomb Dizzy from above, but it's rare that you'll ever end up near them, so overall that part of the game is a lot easier. Other things were made harder, though; I like how the Keldor castle shoot-out is much faster-paced. Oh, and I never found any side exits to the other streets from the river like the NES version has.

Was it a plant? I thought it was supposed to be a volcano off in the distance, spewing molten rock onto Dizzy's location. Anyway, it is also in the Master System and Game Gear versions, only it spews even faster!
