After Twilight Sparkle discovers a new book of pick-up-lines, she wants to bring her friends closer by complimenting them with cheesy lines.

And it does more than bring them closer...

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Twilight stalks and harasses a nine year old filly...but it's in the past, so it's totally legal.

Now with Reading by CaptainBron3y

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'.

In a world where ponies see in grayscale until they meet their soulmates, finding your soulmate is a momentous occasion, where the special connection between you quite literally colors your life. When Twilight began dating Rarity, she didn't mind that she couldn't see in colors.

Or, so she thought, until the day Rarity suddenly could.
