Minecraft wiki entry for Combat, associated text: Allied: Despite dealing no damage, the snow golem's use in combat is not to be underestimated. Defensively, they can either knock enemies away from the player's base, or lure them into a trap. They are very cheap to make, and offensively, they can distract mobs, making them much easier for players to kill, as after being hit by a snowball, they will ignore the player to attack the golem. This allows players to make easy kills on most mobs. They also alert them if a mob approaches from behind, as well as slowing it. If players need to retreat, place a snow golem or two to occupy incoming mobs, buying them plenty of time to escape or let their health regenerate. Unfortunately, they do not attack creepers, so players may want to take a cat with them if possible.
