Lost World (Donkey Kong Land III)
From the Super Mario Wiki
Lost World is a world in Donkey Kong Land III, and is the primary objective of the game, as a contest is held to see who can find the world first. It can only be accessed after Dixie and Kiddy Kong collect all of the DK Coins. Despite the world supposedly being inaccessible to most, there are two factories that have been set up.
