Ice Mountain Zone (アイスマウンテンゾーン Aisumauntenzōn?) is the fourth Zone in Sonic Advance. It is a snowy region with some underwater caves. As with other Zones in the game, Ice Mountain Zone consists of two Acts, with a boss fight at the end of the second.


Ice Mountain Zone is a winter-themed region with mountains in the background. Underwater caves can be found often in the Zone.


Dr. Eggman visited Ice Mountain Zone during his quest to establish the Eggman Empire by finding the Chaos Emeralds and turning Animals into Badniks. Hot on his heels however, were Sonic, Tails, Knuckles and Amy, who came to Ice Mountain Zone, where they freed the Animals and found a Chaos Emerald there. Later, Eggman battled them with his Egg Spider, but was defeated. With Eggman fleeing from Ice Mountain Zone, Sonic and co. followed him.


This Zone features large underwater pathways to go through. There are round frozen shells that may hide Item Boxes or Springs. Some snow on the ground may also stop the playable character and slow them down. Drisames may also break through certain parts of the scenery when approached.

Sonic battling the Egg Spider, from Sonic Advance.

The boss of Ice Mountain Zone is the Egg Spider, which is encountered at the end of Ice Mountain Zone Act 2. When facing this boss, the Egg Spider will crawl along the ceiling, just out of reach, while the playable character wanders around underwater. Periodically, it causes icicles to fall from above: dodge the sharp undersides, but land on top of them to reach the Egg Spider or grab a breath of air. After taking a few hits, the Egg Spider will produces icicles more rapidly. Land a few more hits and the Egg Spider will increase its rate of fire yet again. Hit it a total of eight times on Normal mode, or six on Easy mode, to defeat it.
