Sir Frosty

Sir Frosties are enemies from The Legend of Zelda: Spirit Tracks. They are snowmen found in outdoor areas of the Snow Realm. Forsty Snowmen have a reputation of being friendly and fun, but they are in fact, hostile towards Link. They throw their heads at the Spirits' Train in hopes of derailing progression. They can be blasted away with the use of the cannon.
