Nether hive
The Nether hive naturally occurs in the Nether. It is very difficult to find due to its resemblance with the netherrack. It is home to the Embittered Bee.
When broken with a scoop, Mining Laser, Wand of Excavation, Block Breaker, a Vajra or Quarry it will randomly give either an Embittered princess and Embittered drone. It might give a comb when broken, but not frequently.
