Two deep square (3x3 or something), one villager and a zombie, and a flower of regen (or something)
Then install Tropicraft júst to setup a
beach chair and watch with a Piña colada in my hand.
Edit:
Ohhh, I thought of something better, kinda stolen from DireWolf20's video a long time ago.
Vanilla villager breeder system, then use Railcraft to transport excess villagers to a 'fun' location.
Location: Use Mystcraft to create two very unstable ages (with all the horrors you can imagine that comes with it) .
Then seperate the children from their parents and drop them in the two ages.
Imagine the look on their faces as they are dropped into a world, with no return book, with huge falling meteors, and destabilizing ground underneath them, if not lava outright.
Hmm, I suprise myself o0
