Mob B

Mob B, "The Monster of the Night Skies", is a flying creature that seeks out and attacks players who haven't slept in a long time. It spawns at high altitudes in the air, and attacks in groups. Jeb_ says that viewers should vote for Mob B because there are currently no flying monsters in the Overworld yet. Mob B won the vote at Minecon Earth, and will be added to the game in the Update Aquatic.
