The 雪球发射器 is a weapon which uses 雪球s as ammunition. Once placed, right clicking it will fire a single snowball; holding right click will release a rapid fire of snowballs, with a spread of roughly thirty degrees. It is an uncommon drop from the 小雪怪 in the 地下雪原 biome, with a 1/150 (0.67%) chance to drop.
Similar to the 大炮, the Snowball Launcher can also be triggered by 电线. Depending on where the wire is connected, it will either shoot a snowball (with 1/6th of a second cooldown) or turn to the side the wire is on; these Snowballs are purely cosmetic, as they are not consumed from the player's inventory, and will not deal any damage to enemies.
