I was mining in my 2 day old survival world. At Y level ~13, under an extreme hills biome, I found a cave. This was not your ordinary cave. This was your "Why am I getting THIS excited about a game!?" cave. It was FILLED with iron, lapis, gold, emeralds, and even a few diamonds. Of course, filled with joy and excitement, I mine without torching. I successfully got the gold, lapis, and iron. As I was mining one of the emeralds, I hear a hissing sound. The sound every 20> year old with a computer and credit card fears most. The creeper. It blows up, with the emeralds going down with it. I'm at half-health, and retreating to the diamonds I found. I make a cobble shelter and heal while mining the diamonds. After the diamonds were mined and I was healed, I broke the shelter. I immediately regretted my decision. In front of me was an army of mobs. I know army might seem a bit of a stretch, but this is no joke; there was an army of these things. There must have been at least 4 of every common hostile. I ran towards a vein of gold, and a creeper goes off near it. It flings me into a lava pit. I had a fire prot potion so of course I drank that. It was just after that that I completely gave up on single player survival... Behind me was more of the army (Mostly just zombies at this point; all of the creepers went off). In front of me was a skeleton. With a punch bow. At this point I was mouthing words that would make my grandmother left-hook my poor face into my monitors. The skeleton was shooting at me into the army. I was swimming left and right, until I thought of a new direction: down. Yes, it was perfect. I'd mine down, I'd make a small shelter. I'd be safe. I started my genius plan, and went to the bottom of the pit. I went to my inventory to grab my pick, and I looked to the left of my player. The potion counter. It was at 00:13. Sweating, pushing harder than I should on my keys, and mouthing granny-angering-expletives, I swam out of there and approached the army. They push me back into the lava pit. Remember, the skeleton is still shooting. I try to rush the damned archer. 00:06. I'm at the shore. It shoots me. 00:02. I'm on land, hitting the skeleton. I kill it. 00:00. A creeper arrives, and blows up. Into the lava. With all of my diamonds, emeralds, gold, iron, and lapis. I haven't played single player survival since.
Tl;dr: Creeper blew me up. I need a new mouse.
