The light in the eye sockets of the skeleton flickered faster and faster, clearly excited upon seeing so many people's bone parts. It immediately began rummaging through the pile of human bones to find ones suitable for itself.
Soon, it chose what it considered the perfect skeleton for itself, tidied itself up, then dug out the flame from its own skull and stuffed it into another skeleton's skull which had a larger forehead, then secured its own skull in place.
This time, it finally looked like a normal human skeleton, no longer a motley collection of assembled parts. It appeared much more orthodox, examining its body up and down, the flame in its eye sockets flickering as if it were satisfied with its own appearance.
After all these preparations, it seemed to remember something, immediately grabbed a skull, turned, and ran outside without stopping.
