One night, Pinkie Pie stays up late to watch a couple of old horror movies. It should be fun, right? How can a black-and-white feature like "Night of the Changelings" be at all terrifying?

...Very, very terrifying, as a matter of fact. So much so, that the next day at school Pinkie is grappling with the aftermath of horrible nightmares, and the creeping fear that any of her classmates could be a slime-dripping alien bug monster in disguise. Now her friends have to find a way to calm her down, and hopefully do so *before* she goes completely off the deep end.

Shamelessly inspired by the SpongeBob episodes "Krab Borg" and "Fear of a Krabby Patty".

Rated T just for the sake of caution.
