Everybody Cuddles! · 1:37pm Apr 1st, 2016
I think that I should resolve all my major character arcs by having everybody cuddle.
First, all the Mane Six cuddle. Then Spike and Starlight join in. Hankey pankey with Rarity ensues. Starlight feels left out so Sunburst snuggles into her. The Princesses show up and there is more cuddling. The cuddling with Twilight and Luna has reincarnation romance overtones. Cheese Sandwich and Discord come out of nowhere, which is actually plausible for those two. More cuddling. Discord separates some of his body parts for anatomically-impossible cuddling. The Cutie Mark Crusaders show up and realize that their Cutie Marks actually mean that they're cuddly. So they cuddle.
Everypony in Ponyville starts cuddling. The ball of cuddliness now contains thousands of Ponies and other creatures; the Princesses cast life support spells to support the immense cuddling. An emotional attraction is exerted on every being in Equestria. They all join the immense cuddle. The Smooze joins in making a sort of section that's like a nut pudding with the Ponies being the nuts. Everyone is cool with this. The Sunney Towne Ponies are all magically-resurrected so they can join in the cuddling.
There's a lot more cuddling. Also cuddling, and cuddling.
Eventually, Flurry Heart gets her Cutie Mark. She's the Princess of Cuddling! And this results in an affection singularity that breaks through into the Shadowverse.
There's an explosion of affection and the Shadows all stop being evil and start cuddling each other.
The Shadow Wars end, not with a bang (that's the Winningverse / Degradingverse) but a cuddle.
April Fool's! 
I'm reminded if Gabor Zovanyi's evocative image of a ball of human flesh expanding outward at many times the speed of light, only fuzzier.

Yes, in reality if we just smooshed tens of millions of Ponies together, the consequences wouldn't be pretty. As in Hieronymus Bosch levels of non-pretty.
