Creeper 

A green, soulless monster that is truly feared. It stands up like a human, but has four legs and no arms. Creepers only comes out at night time, never smile, and refuse to go near light. Creepers usually wander aimlessly, looking straight at you occasionally. If you get too close to a Creeper, however, it'll begin running straight towards you. Once it touches you, it'll hiss for a few seconds, then explode. If you kill a Creeper without it exploding, gunpowder can be found in it's corpse.

Steve: *places door* "Ahh! After 5 hours of straight work, I FINALLY finished making my stone castle."

Creeper (From Behind): "TSSSSSSSssssssss..."

Steve: *turns around* "OH MY GAW..."

Creeper: *explodes*

Steve: *dies*
