Snow Globe

The Snow Globe can be obtained from opening presents, but only in hardmode worlds. The chance of getting a Snow Globe is 1/14 or 7.14%. When used it summons the Frost Legion, an event very similar to Goblin Invasion. There are three kinds of enemies that will be summoned:
 * Snow Balla, which throws snow balls
 * Mister Stabby, who has a knife
 * Snowman Gangsta, with a Tommy Gun.

The Frost Legion should only be summoned once the player has acquired hardmode gear; they are considerably stronger than the Goblin invasion.
