Snowman Gangsta

Snowman Gangsta is an enemy in the Frost Legion. It carries what appears to be a tommy gun and shoots musket ball-like projectiles at a slow rate. He can only shoot left or right, so managing to angle oneself above or below him is an effective technique. Trapping him in a pit filled with water is an effective way of trapping him, but without a ranged weapon, that leaves no way to kill him.

Trivia

 * Snowman Gangsta and Snow Balla have the most similar appearance out of the three Snowmen, and both shoot projectiles.
