I would be a creeper, but for a further purpose than the two above me. I'm very single and shy, and I just want a hug sometimes, but when a companion tries to hug me I get mad. :[ <-- if you form this in a machine talk, it looks like a creeperface. Real tale.
probably some diamonds and other ores when to near to lava or slipping. I'm usually cautious not to die and normally keep just a basic/replaceable set of resources on me. I also don't usually create any shield, so I don't have to fear about all that metal being thrown away.
