[X] Kill Stuff And Make A Big Pile of Bones Shaped Like A Snake. The orks agree; that snake was zoggin' cool. Bones are also shaped like snakes. Therefore, if they make a pile of bones shaped like a snake, that's like doubly-snake-like and they might get the snake's powers.
I mean... I'll be entirely honest here. I'm not voting this way because I want anything, exactly, except... that is a damn cool image. The Orks are absolutely correct there and I'm convinced we can make this look like something out of a heavy metal album cover. Overlap some rib cages so the thing has a double row of spikes down its back and all the teef.
And you can always make a snake longer. Just keep making more snake.
We could even make it coil around the pit after enough murder and munching.
