- Icecap Zone

If you're playing as Sonic & Tails or Sonic Alone, Sonic will land on a skateboard and ride it through the level for a while. Eventually, you'll crash into a wall and fall into a hole. When the avalanche occurs, jump up to emerge from the snow. If you're playing as Tails, you'll start the level at this point.

At the start, when you go down the slopes, Tails can lose all his lives, causing a Game Over to appear on the screen. This glitch can prevent you from completing the game as Tails, but if you can fly past the slopes, you can avoid triggering the glitch.

Spin Dash through the wall and continue onward. Go past the Starpost and jump on the spring. Head right and break the ice surrounding the switch. Press the switch to cause the ledge to collapse. Drop down and run past the ice blasters. If you get hit, you'll be frozen in ice. When the ice breaks, you'll lose all your Rings or lose a life. If a second player is controlling Tails, he/she can break the ice to free Sonic.

Slide down the slopes, and jump onto the platform to the left. Use the platform to break through the walls. Smash the ice surrounding the springs and jump up them. Spin Dash to move the swing lifts. At the top, go down the slope. Hop across the stalactites one by one to avoid being hit by them and knocked into the frozen spikes.

Go past the Starpost and push the platform to the right. Use the ice block to break through the walls. Run right and press the switch. Drop down and Spin Dash to move the swings. Go past the Starpost and head right.
