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 snowy biomes such as ice plains.

Structure
Igloos may spawn as a single room by itself, or with a basement of stone bricks and variants. Within the basement are treasure chests, a cauldron, a brewing stand, 2 red carpets, 3 spruce stairs, along with a villager and zombie villager of random professions trapped in iron bars. A trapdoor with ladders leads down into the brick basement, with 2 torches.
