Meet Deadpool: a mercenary, an assassin, and overall, an antihero in the Marvel Universe. He has the ability to quickly heal, thanks to some tests made from the Weapon X Program that healed his incurable cancer, but left his mental stability down the toilet. If any of you know the real Deadpool, don't worry, he's not the same silent freak played by Ryan Reynolds in the piece of s**t prequel starring Hugh Jackman as a short guy with metal claws. If you have no idea who or what is going on, please, look it up.
Meet Equestira: A magical land that hosts many mythological creatures, but mostly god horses, unicorns, pegasi, and boring horses. Everything is ruled by two god horses; Princess Sun Butt and Princess Moon Cheeks. Sun Butt rules during the day, controls the sun, protects land from monsters, indulges in male anatomy shaped fruit & cake, and abducts children... at least that's what wikipedia says. Moon Cheeks rules the night, controls the moon, plays with people in the 'apple master race', haunts children as the next Freddy Krueger, and plans how to take over the world when no one is watching. There's also six horses that act as the 'mane' stars and a bunch of other background & side characters that this Fan Base loves... like this girl that... loves... rocks. I don't get it.

Spike wants to ask Rarity to be his special somepony for Hearts and Hooves, but he doesn't know the right way how. Meanwhile, Rarity gets a hair-brained scheme for her own little Hearts and Hooves celebration, that goes very awry!

When Fluttershy helps Twilight out with some spells she has never tried before, they end up turning a piece of candy corn into a real, flesh and blood, breathing mare. While they try to figure out how this happened, the mare leaves an impact on everypony she meets.

Uncle lives a very fulfilling life at his antique shop. It's peaceful and quiet for the most part, just how he likes it. Of course, he's a skilled chi wizard, so he knows better than to actually let the universe know that he's content. So he complains.

A lot.

Then one day, a basket containing three infant magical ponies arrives, and his peaceful life goes out the window...to be replaced with, perhaps, something a little more than contentment.

The universe, apparently, is smarter than he gave it credit for, because now he has "Three More Things!" to complain about to hide just how much they mean to him.
