Iceball

Big Icedus is a mini-boss from Sonic the Hedgehog 3, as well as its locked-on form, Sonic 3 & Knuckles. It is encountered in the first act of Icecap Zone.

Big Icedus has the shape of a snowman that hovers in the air. The robot is too high to reach at first, and will attract a shield of eight giant snowballs for protection. After hovering around the screen, Icedus will throw its snowballs in the air, and try to hit the player (which need to be avoided with good timing). The best chance to hit Icedus in the air is when it is throwing up its snowballs.
