Mr. Blizzard

Mr. Blizzards are enemies in Super Mario 64. They are snowmen with gloves that throw snowballs at Mario. They usually appear in Cool, Cool Mountain and Snowman's Land. Similarly to a Mr. I, they are defeated by circling around them.

In some personalized copies, Mr. Blizzards can potentially be lured into water. This can cause the Mr. Blizzards to melt, providing a secondary way to defeat the enemy.
