MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

Princess Celestia has sent the Elements of Harmony to persuade a human to stock Equestrian goods in his stores. When he asks to test the products, it doesn't go according to plan. And when a certain party pony gets involved, things only get worse.

But thankfully, it all leads to a wonderful new idea...

COMMENTS CONTAIN SPOILERS

Nathan Frédérick Nadeau Bergeron doesn't come from an ordinary family. They have resources—maybe even enough to survive the end of the world. As CelestAI gradually supersedes the instruments of human civilization, the greatest dangers are often entirely natural. But he's determined, determined to survive no matter what it takes. Nathan has given himself a mission: to record the end of humanity.

Now if only that pony would leave him alone...

What happens when ponies try to force humanity into their hooves? Well Jenkins of course!

June 2nd, 1942. Two days before the Battle of Midway, two days before the tides of power shift in the Pacific theatre and a new threat looms over the horizon. Multi-coloured ponies talk of a "better existence" and "peace and harmony" but at the cost of losing your humanity. Naturally humanity "politely" declines this offer and the war begins, enemies turned allies face the... well to be frank, the shortest war they've ever fought.

Also did I mention how much I hate The Conversion Bureau?

Warning: Stupidity and terrible writing ahead. Health risks include, but are not limited to, severe brain haemorrhaging, stroke and vomiting.

Continue at own risk.

I do not own anything My Little Pony related in this story, other than the story itself.

We've all seen various HiEs of varying natures. From the instant-friend hot garbage, to the crossovers, to the more serious ones, to humans being the size of ants in comparison. But what if we flip that last one around? And what if... the human in question was just a child?

After agreeing to Twilight's proposal of having a date in an alternate universe, Rarity finds herself contemplating many things, including but not limited to: what it means to be a human, how are you supposed to walk on two legs, meeting teenage versions of yourself and your friends, and last but not least, questioning your entire relationship and the nature of soulmates.

Going on an inter-dimensional date with her marefri—sorry, girlfriend—was not supposed to lead to the existential crisis of a lifetime, but there was Rarity anyway.

Set in the same continuity as "The Swap". Absolutely not set in the same continuity as "Your Own Worst Enemy".

Christopher Boatner is a diplomat from Earth, in Equestria to interview Princess Twilight Sparkle to understand pony culture and customs better. Thing is, he's unprepared for what amounts to one of the biggest discoveries between humans and ponies ever. Bad puns. A lot of them. Along with general ignorance about the creepy nature of cutie marks. Will Chris be able to handle the multitude of horse puns? Read to find out!

A big thanks to my editors Kaidan and The 10th Doctor, along with my pre-readers Skeeter The Lurker and Mr101 for all their help!

This story is a sequel to The Cuddlequest of Earth

The ponies came to Earth. They saw humans. They cuddled humans. And yet... in yet another different time and in yet another different place, things have been... reversed. The natural order of things is just... reversed. How?

Who cares? Let's watch as Princess Celestia discovers a form of friendship magic more potent than she or even her student Twilight Sparkle has ever had to contend with.

Time and time again, Equestrian magic has proven to be dangerously unstable in the human world. SciTwi realizes that if she wants to study magic safely, she needs another source of arcane power.

So she decides to steal Christmas Hearth's Warming.

Naturally, Sunset is on board.

During Spring Break, Sweetie Belle decides to help her sister deliver a dress for Sunset Shimmer. What she doesn't realize is that the former unicorn has a secret. Despite spending so much time as a human, Sunset still finds clothing uncomfortable and enjoys living in the buff whenever she can.

Although reluctant to embrace the idea at first, Sweetie decides to follow Sunset's example and try the clothes-free lifestyle for herself. The young teen comes to realize that she loves the feeling of freedom it offers and wants others to enjoy it too. Thus, the Natural Living Appreciation Club was formed.
