In Adventure Mode, the mountain path is dominated by Freezie-pushing Topis and Polar Bears that force the stage to "jump" upward when they hop. Players can jump along the top of the stage to force their way higher to quickly face-off against the Ice Climber team, or climb higher to reach the two platform summit.
In All-Star mode, this stage is played on when the player faces the Ice Climbers and any of their teammates.
This stage comes from Ice Climber. The goal of Ice Climber is to try to get to the top of the level while dodging obstacles and enemies. In Ice Climber players would have to jump to break through blocks in order to progress through the stage. This stage also have destructible blocks that can be destroyed to get through. Also in Ice Climber are icicles that would form and fall. If the player got hit by the icicle he or she would lose a life. Icicles can be seen in this stage, but they do not damage players. If the player takes too long in a stage in Ice Climber a Polar Bear would appear and jump to make the screen scroll up. This stage scrolling down in this stage could be a reference to the Polar Bear being up to move the stage down (considering the levels don't move on their own in Ice Climber like it does here). 
There are two music tracks for Icicle Mountain. One is the title screen of Ice Climber (which is also the same track used for the bonus stages) mixed in with the music used for the mountain stages. The other music track is the music for the mini-game Balloon Flight from Balloon Fight. 
Unveiled at E3 2001, Icicle Mountain is a stage that constantly moves up or down (mostly up), therefore making it a sidescroller. It moves infinitely up/down, although the speed varies. It has platforms that are flat as well as diagonal. There are ice blocks that can be destroyed with one hit, both large and small ones. Many sections of platforms are slippery as they are made of ice. There are also platforms that drop if one stands on them too long. If playing as Pikachu or Pichu, once using Thunder, it is instantly rendered useless, due to the fact that floors are constantly generated, permanently blocking the move.
 Tournament legality
Icicle Mountain is universally banned at tournaments, primarily due to the fact that its primary focus for players is to survive, rather than actually fight. Additionally, it heavily favours characters with superior jumping prowess. The upper blast lines and horizontal blast lines are close to the stage, allowing for some very early KOs, and there are impassable platforms throughout the stage that can block a potential KO. The frequent blocking of the lower blast line also undermines spikes and meteor smashes, as well as minimising edge guarding skills.
 Unused versions
When the game is hacked in the Debug Menu with cheat devices such as Action Replay, two alternate versions of Icicle Mountain can be found: 10-2, and IceTop. Under most circumstances, selecting either stage causes the game to crash; the use of other hacks can, however, allow for the two to be selected.
When accessed, 10-2 and IceTop are effectively the same as Icicle Mountain, except the two do not play any music. The ultimate use for the two stages remains unknown. 10-2 has been speculated to be a second Ice Climbers stage in the Adventure Mode, as the Icicle Mountain stage in the mode is Stage 10. IceTop has been speculated to be its own map, intended to be the "top" of Icicle Mountain. These theories, however, cannot be verified in any way.
- Any AI character tends to SD easily when the stage starts scrolling quickly upwards. This is due to the fact that the AI will only ascend one platform at a time. Frequently, this leads to the character not moving quickly enough to escape the lower blast line, resulting in an SD.
