Pacifica
From RWP Wiki
Pacifica is a world in the Game Boy Advance port of Donkey Kong Country 3. It is exclusive to this version, meaning it has all-new levels that were absent from the original SNES version. Pacifica becomes accessible once Dixie and Kiddy Kong have obtained the Turbo Ski from Funky Kong (that is, after the player has completed Cotton-Top Cove and Mekanos. The entrance to Pacifica is located underneath a lake above a waterfall in the Northern Kremisphere. The boss of Pacifica is Barbos who was located in Razor Ridge in the original version.
Barnacle Bear has been moved here, having been located in Lake Orangatanga in the original version. Also, interestingly, the Swanky's Dash for this world is located in a cave, unlike most other worlds.
