Papyrus's exuberance is actually kind of refreshing. It's been awhile since Mettaton has really hung out with the skeleton since arriving here and even in situations like this that are a little more tense than they seem, it's nice to see how gung-ho he is. And easy to feed into the energy.

Right when Papyrus throws his bones, Mettaton kicks a leg out and strikes it against the door. Between the two of them the door buckles and groans, relenting after a very short-lived resistance. It's open now, and what lies beyond is an inky blackness that would set the hair on the back of Mettaton's neck to stand if he had any there.

"...well that doesn't look good."
