This Zone is basically a replica of Sonic the Hedgehog 3's IceCap Zone, complete with that Zone's snowing effect, albeit with different graphics. It does, however, have much larger underwater areas that span both Acts. It should be noted that, unlike the Sega Mega Drive Sonic games, air underwater only lasts for 18 seconds, and there are no chimes to indicate time spent underwater—only a counter for the last five seconds of air.
A gimmick that can be found in this Zone are geysers that launch platforms upward, all of which are found only in the underwater sections of Act 2. Thick snowdrifts will slow the player down when walked in, necessitating the player to jump repeatedly to move more quickly over them.
|Drisame — Sharklike Badnik that appears under walls underwater, a lá Grounder.|
|Kuraa — Jellyfish robot utilizing electric shocks. Only found underwater.|
|Pen — Penguin Badnik with a which also attacks using snowballs.|
|Yukimaru — Pandalike robot which uses snowballs to attack.|
Special Spring location
This is also the only Zone in the game to have a Special Spring in both of its Acts. Other Zones in the game typically only have a Special Spring in one of their Acts.
The first Special Spring, located in Act 1, requires the player to follow the top routes as much as possible until they find a set of three swinging platforms. They should ride the platforms and jump to a piece of land with a diagonal spring pointing left, and carefully cross multiple pieces of land and using springs until they reach the Special Spring. Tails can easily reach this spring by flying upwards after passing the first Checkpoint.
The second Special Spring, located in Act 2, also requires sticking to the higher routes as much as possible, and is found past the halfway point of the Act. It is placed on a ledge to the right of three rotating platforms.
