The Kaizoku Snowball (海賊スノーボール Kaizoku sunōbōru?, lit. "Pirate Snowball") is an enemy that appears in Sonic Rush Adventure. It is a mass-produced Badnik model created by Dr. Eggman and Dr. Eggman Nega.
Kaizoku Snowballs are tiny blue robots with humanoid bodies. They have silver limbs and heads with a black circle in the middle of their bellies, which they shoot energy balls from. They appear to have white faces with black eyes.
Kaizoku Snowballs appear in Blizzard Peaks, Hidden Island 12, and Hidden Island 13. In gameplay, they hide inside snowballs many times larger than them. They will occasionally come out of hiding to shoot at the playable character. Once their snowball is destroyed, they will simply wander around until they are destroyed.
