I've also found my first diamond when I was looking for a slime because I heard "FAP FAP FAP".
I must find a way to mark the way to exit. I think that "redstone road" would be good, what do you think? Because the MiniMap Mod shows the surface only.
Now I'm watching...
OMG IRON! But how to get through?
A dark and scary cave
Diamonds, I'm lovin' it.
ROPE ME PLEASSSSSSSSSSSSE
I had taken this screenshot and then I felt down, le fu-
He jumped into lava just a second after I took this screen
What are your last words?
I've met this slime when I respawned after death and went to take my items. It hadn't been there before I died.
