Ice World is the fourth world in DK: King of Swing. It can be accessed once Donkey Kong (or Diddy Kong in Diddy Mode) completes the Aqua World area. After completing the four levels, the Kong can fight the world boss, Sassy Squatch.
As its name suggests, Ice World primarily consists of snow and ice-themed levels. To the west there is a large ravine with moving Peg Boards and a snowy forest inhabited by Mini-Neckies. In the northern part, there is a large frozen castle. To the south of the castle is a body of water with the ruins of a building. The world boss, Sassy Squatch, is fought in the southeast corner of Ice World.
If Donkey Kong obtains every medal in the Ice World, the player unlocks Obstacle Race 3 for Jungle Jam mode in both single player and multiplayer.
