Gargamel

This is the strange valley in which you will find yourself if you seed Minecraft with the word gargamel, in lower case with no spaces or punctuation.  You spawn in an under ground cave that has a sliver of a few blocks of light somewhere above.  If you manage to spot this light, you'll be able to dig and claw your way to the surface.   If you spawn at night, in the cave, in the total darkness, well then the zombies will get you.
