I know that seeds aren't as good with letters, so I need a way to convert the word Herobrine into numbers. So I thought of getting every letter's value in the alphabet (A being 1, Z being 26). I ended up with 805018015020180901405.
This is an... odd seed, to say the least. It's a taiga biome I think. It has tiny floating chunks of land, and some strange, bent trees, but oddest of all is:
I tried the seed 'herobrine' as letters, and got some interesting things as well. The map has some incredible rock formations, tall cliffs etc, as well as the strangest little cave I've ever found. Inside was a single zombie, and a strip of grass. Yup, grass, about 5 layers down, with no connection to the surface.
