After a few long years of traveling through Equestria, Big Macintosh has finally returned to Ponyville, and Spike, now a teenager, is happy to see him. In fact, he's decided to be kind enough to bring him to Soarin's housewarming party. No matter how reluctant Big Mac is, he tags along with his dragon buddy anyhow. The plan was to get to know the ponies that he barely knew before leaving on business, and most importantly. Party like there's no tomorrow.
Which is just as literal as it can get. What they didn't plan on, was an earthquake that would cause windows smashing, lamp posts falling, and giant demon pits opening up...okay, that last one might not be so natural. Either way, the party guests would get sucked in, leaving Spike, Big Mac, Soarin, Caramel, and Doctor Whooves to fend for themselves during...the Apocalypse.

Based on the movie, "This is The End" by Seth Rogen, and Evan Goldberg.
