Snow Globe

The Snow Globe can be obtained from opening presents, both in pre-hardmode and hardmode worlds. 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.

Caution should be used if the player summoning the Frost Legion is inadequately geared (i.e. in pre-hardmode items), as the enemies spawned are much stronger than those of e.g. the Goblin Invasion.
