There could be a fan fiction where Maud Pie, as a human, goes on a road trip. Along the way, she meets various quirky characters and has strange but enlightening conversations. Her matter - of - fact way of speaking might lead to some really funny situations during the trip.
You can start by looking on fan - fiction websites like Archive of Our Own (AO3). There are often many My Little Pony - related fan fictions there, and you might find some great Maud Pie human fan fictions among them.
One possible idea for this fan fiction could be that the snake is a magical creature in a fantasy world. It discovers a pie left by a human traveler. The snake, being curious, decides to eat the pie. As it takes a bite, it gains some strange powers related to the ingredients of the pie, like the ability to fly if the pie had feathers from a magical bird in it.
Well, it could be that the dragon is on a quest to find the most delicious pie in the land. After searching far and wide, it finally discovers a magical pie. The dragon then has to figure out how to eat it without using its fiery breath and ruining the taste. So it tries all sorts of comical ways, like using tiny utensils made for fairies.
Sorry, I'm not aware of specific 'eating a pie' fan fiction. You could try searching on fan fiction websites like Archive of Our Own or FanFiction.net.
A plot twist could be that the pie is poisoned. Just as the snake is about to finish the pie, it starts to feel ill. But then it turns out that the snake has a special immunity to the poison that was put in the pie by an evil character who wanted to harm anyone who ate it.
It depends on your perspective. Some might consider it realistic as it could potentially mirror real-life situations and emotions, while others might not see it that way.
Perhaps there's a knight who is supposed to protect the pies from the dragon. But instead of fighting the dragon, he ends up making a deal with it. The knight will supply the dragon with a certain number of pies every week in exchange for the dragon not attacking the village.
Begin by brainstorming some ideas. What if Shadow accidentally enters Pinkie Pie's world? Or what if Pinkie Pie decides to cheer up Shadow when he's feeling down? Once you have a basic idea, start writing the opening scene. Describe the characters and the setting vividly. For instance, if it's in Ponyville, talk about the colorful houses and the friendly ponies. As you write, let the personalities of Shadow and Pinkie Pie guide the story. Pinkie Pie might bring in lots of humor and chaos, while Shadow could be the voice of reason or add a bit of mystery.
