Igloo

Igloos are structures that are naturally generated in snowy biomes. They are round structures constructed primarily of snow blocks.

Generation
Igloos naturally generate in the Ice Plains and Cold Taiga biomes, but not in Ice Mountains, Ice Plains Spikes, Cold Taiga Hills, or other variants.

Structure
Igloos are composed of snow blocks, sheltering a carpeted interior containing a bed, furnace and crafting table.

In half of the igloos, a trapdoor can be found under the carpet, leading down a long ladder shaft to a basement. This passageway and the basement are built from stone brick, some of which are monster eggs. In this basement is a brewing stand, a cauldron, a chest, and beyond the far wall, behind iron bars in two different cages, are a villager priest and a zombie villager priest.

The cauldron is $2/3$ full, and the brewing stand contains a splash potion of weakness and an empty bottle.

Loot
In addition to this loot, one golden apple will always appear in these chests.
