Sherbet Land (world)

Sherbet Land, or Sherbet Island, is a secret world in the game Wario Land: Super Mario Land 3. It is completely optional and can only be reached by a secret exit in Mt. Teapot. Sherbet Land is a giant iceberg floating off the coast of Kitchen Island. Since it's an iceberg, its levels consist of lots of water and ice; several levels also have enemies such as D.D. and Pirate Goom frozen in blocks of ice. The boss at the end of this world is a Penguin.
