IceCap Zone's bosses involve ice-based attacks and slippery surfaces, adding an extra layer of challenge to the encounters.
Mini-Boss: Ice Mobile
- Location: IceCap Zone Act 1
- Description: A large robot that fires ice projectiles and creates ice spikes.
- Attack Pattern: Moves back and forth, occasionally firing ice projectiles or creating ice spikes on the ground.
- Strategy: Attack the Ice Mobile when it's not attacking. Wait for it to finish its attack, then jump and hit its cockpit. Be careful of the ice spikes, as they can be difficult to avoid on the slippery ground. Three to four hits will destroy it. The Aqua Shield's protection from freezing water can be useful if you fall into the lower area.
- Weakness: Cockpit when not attacking.
- Reward: Clear path to the next section.
Boss: Egg Mobile (Ice Drill)
- Location: IceCap Zone Act 2
- Description: Dr. Robotnik in a giant ice-drilling machine.
- Attack Pattern: Moves across the screen, periodically dropping ice blocks or firing ice projectiles.
- Strategy: Attack Robotnik when he is not drilling or firing. Wait for him to finish his attack, then jump and hit his cockpit. Be careful of the falling ice blocks and ice projectiles, as they can be difficult to avoid in the confined space. The slippery floor adds to the challenge. Seven to eight hits will defeat him.
- Weakness: Robotnik's cockpit when exposed.
- Reward: Progress to Launch Base Zone.
