|Dr. Lunatic World|
|Release Date:||5th May 2000|
Being one of the original five worlds (the others being Spooky Forest, Dusty Desert, Cavernous Caves and the Crazy Asylum of Madness), it is part of the world selection globe in the original game and does not have to be accessed via selecting "Custom World". Beating it is a requirement to access the Crazy Asylum of Madness in the original game. In Supreme With Cheese, Icy Mountain is one of the worlds selectable from the start, but is no different from other worlds in terms of significance.
In Supreme With Cheese, the Icy Mountain world is unique for periodically changing between daytime and nighttime, allowing the player to access different levels depending on the time of the day, with each daytime level having a nighttime counterpart.
