Ice Balls are diminuitive, orb-shaped robots created by Dr. Eggman. They appear in the Ice Cap stage of Sonic Adventure and they drive around in small walking vehicles that look similar to Dr. Eggman's Eggmobile. These walkers are armed with a freeze jet that can blast enemies with cold gas and freeze them solid. If the Ice Ball's walker is destroyed, the robot will jump out and run around in a panic.
