I've always wanted a creeper character, so I decided to draw one
It's kind of a weird mix between creepy/cute O--o but I like it.
(I didn't think the shading/lighting would turn out so well, holy crap)

So anyway, the reasons behind this anatomy:
1. I think creepers would look more humanoid to enhance the creepy factor (and lure in unsuspecting minecratfiants)
2. Instead of a hunking chunk of TNT in their stomach, I think creepers have two sacks of chemicals that explode when combined.
3. Those sacks can be removed, or a creeper can be malformed and born with out them(which is what happened to this guy)

So there ya go, my headcanon stuff. *u*

Gosh this guy is cute.
I'm gonna hug him to death.
