Snow Balla

The Snow Balla is a Hardmode enemy that only spawns during the Frost Legion event. It throws snowballs at the player that form Snow Blocks on impact with other blocks, similar to the attack of the Antlion. The Snow Blocks can also spawn in the air if Snow Balla throws it into the sky. If it falls in a pit, it is possible for it to trap itself.

Snow Balla is immune to the Poisoned, Venom, On Fire!, Shadowflame and Cursed Inferno debuffs.

Trivia

 * When the Frost Legion was introduced, Snow Balla's attack was similar to that of a thrown Bomb. This was likely changed due to its destructive nature.
 * It is possible the name is a reference to a gang named Ballas in Grand Theft Auto: San Andreas.
 * If the two words are combined, it is read as Snowballa, a slang of snowballer, which fits the description of what it does.
