Donkey Kong Country 3: Dixie Kong's Double Trouble!
The Knatilus features a couple of changes. One is when Knautilus emerges, the water turns into lava and the entire world, including the stages turn red. This no longer happens in this version. Another is that the water is the only thing that turns red. A third thing is that Dixie and Kiddy are able to swim in it to the Knautilus rather than simply hopping on it in the SNES version.
