I was going for C, but now I don't know if I should instead go for D. I initially loved B as something to make players use beds, but there are a lot of problems Mojang would need to fix to make the mob be fun and interesting instead of annoying. C became my favorite due to the idea of how it could change enchanting mechanics forever. Now I'm wondering about D because it could make the Nether even more exciting, instead of becoming bland after a while. It would also act as a way to relieve tension if the player ran into it randomly. I'll have to think...
