I've been meaning to do this for awhile. The Mob Saloon in Slamacow's animation was quite adorable, I just really wanted to replicate it. While it's not 100% perfect, I'd say it's at least around 98% perfect.

World demo and schematic included, as always.

Note: For the schematic, it's a huge stone block on the outside (there are no entrances in the video), I marked the top with dirt where you can safely dig and fill up without disturbing anything.

Also, please support the original animation by Slamacow. http://www.youtube.com/watch?v=OWmBj9Fw3Qo
