Once I'm able to get my hands on roughly 15 stacks (960 blocks!) of green wool, you guys can except this to pop up on the server:
Yeah, that's right. I build a giant Creeper.
The plan is for it to be a sort of "shrine to the creeper god", to appease the creepers and protect the land. When it's all done I want him to be standing on a hill of cobblestone that's also covered in 3x3 "TNT" blocks (made using red and white wool, not real TNT).
Beside him you can see my other two "mini creeper" statues, one of which is made entirely of mossy cobble (which doesn't look as good as I hoped it would :P)
Now, I just need to find a place to put it..
