The Super Duper Savanna Biome! (extreme hills savanna)

So I was just trying to find a decent empty seed to do stupid things in, and of course I had to be the one to find this... this.... thing. I hate it. That's why I'm making all of you see it and maybe someone will enjoy it.

The first picture is what you should see when you spawn in, if it's not what you see either I messed up or you did. Might be my fault but probably not bro.

The second picture is a village thats there (the loot is ok but not great) which you should pass by to get to the mountains.

And last but certainly not least, the third picture is the Extreme Hills Savanna.
