So, you were in the cavernous caves of the Overworld, mining away at the stone walls in search of diamonds. The caves were huge with lava flowing through some parts of the walls with several lava pools lighting up the place.
You couldn't mine without having to fight a few mobs though. You fought a few zombies and a skeleton that almost got you from around ten blocks above you! Cheeky little thing even if they didn't actually have cheeks. You've seen that the mobs have gotten a little stronger... but it's probably nothing.
You finally go mind and find many ores. You found plenty of coal, some gold, some Redstone, some iron, but no diamonds. You eventually find a sort of passage way. It's just a long tunnel in reality but it's too even to be considered natural. You go in in hopes of finding those precious diamonds...
It's extremely dark in there so you put down torches as you go. At one point, you put down a torch to see two large masses. The first mass looks at you with their purple eyes before disappearing, leaving purple smoke and a block missing from the wall. The other mass turns to you, looking down at you. You realize it's a Creeper but... massive!
"TSSSSS!"" ** The massive Creeper looks down at the torch you put down, pressing its muscular self against the wall in... fear? It stares at the flame in terror as it shakes, absolutely terrified of the small fire. It seems like it could explode at any moment!
