Muffins at the End of the Universe III

Twilight Sparkle is facing the possibility that she may never return from a sunless, moonless, toxic wasteland, millions of years from civilisation.

It's Nightmare Night, and the scanner is clear (with the exception of a few muffin crumbs) for the first time in four months. Venturing outside, Doctor Whooves is delighted to find evidence of an alien intelligence, but everything is not quite as it seems.
