Do you all live in caves? Or is it like fully furnished homes???
(Outside)
Outside, The Door opens with a redstone mechanisms. It's basically a slide door. At the beginning, it were build to hide from the Humans, so they could live peacefully inside The Cave.
(Inside)
Meanwhile, inside (and nowadays), it's all furnished. They have a bedroom for each one, a living room, a kitchen and a Nether Portal.
— It's. . . Somehow k-kind of both. . . At l-least for us?. . . We don't know i-if any other mob lives li-like this, honestly. . . —
— OH! OH! We should be cave decorators!! —
— Haha! P-perhaps we should! —
It took them ages and adaptation to turn the literally hole where they were living into the home they have today.
