I made a giant spawner room in the desert and it is attached to a ravine with alot of lava ,water ,and other stuff and took alot of screenshots . there are creepers ,spiders ,zombies ,slimes ,skeletons ,and spider jockeys. the slimes are allways jumping in the lava. ,haha. slimes are dumb! there are pockets for the monsters to hang out on so they don't get killed .
