I like the idea of slimed and in general non hostile mobs. What if there were little enemies the size of the smallest slimes, or maybe even slimes that could spawn in your bed just to get inside your house.
NO. For obvious reasons, having a mob spawn in a bed, hostile or non-hostile, would defeat the purpose of beds, would it not? Because that I think that a mob underneath/on top of you would wake you up.
Yes I do
EDIT: Also totally pointless.
How did I escape? With difficulty....How did I plan this moment? With pleasure
