Once upon a time, in the magical land of Equestria. There is a mare named Derpy Hooves. Derpy Hooves is a cross eyed pegasi with a grey coast and a blonde mane. Derpy loves to eat muffins. Her favorite flavor is banana nut muffin. One day, Derpy decided to go on an amazing adventure. One Day, Derpy Hooves and Doctor Whooves were having a special lunch at Sugarcube Corners. They were eating some delicious muffins at the cafe. Then Derpy Hooves say a balloon stand. It was being supervised by Pinkie Pie. Derpy Hooves wanted a balloon so badly.
"Dr.Whooves?" asked Derpy.
"What!?" Doctor Whooves replied.
"Can I get a balloon?" Derpy told the doctor with a smile.
"What for?" The skeptic doctor asked.
"You'll see!" Derpy said with a smile.
Derpy Hooves is really really excited to buy a balloon. She bought the balloon at a balloon stand run by Pinkie Pie. She try to inflate the balloon with her mouth. It didn't work because she wasn't trying hard enough. But then she decided to get a bicycle pump and pump up the balloon. The balloon exploded into pieces. So what did Derpy Hooves did next...
...Derpy put the end of the bicycle pump in her mouth to see if the air was pumping hard enough. Because she didn't understand why the balloon exploded. Dr. Whooves tried to warn Derpy Hooves about the dangers of pumping air into your mouth. But Derpy ignored The Doctor anyway. Derpy told Mr.Whooves.
"Your not a doctor Doctor Whooves. I am a professional at inflating balloons. I am going to test this pump on me no matter what."
Derpy put the pump in her mouth and pushed her hooves up and down on the bicycle pump. She pumped as hard as she could. Than something very strange happened to her.
Derpy felt really weird. Her belly was starting to grow every time she pumped air into her body. She felt a funny feeling that she was becoming a balloon. Pinkie Pie decided to pick up the Bicycle pump and use it on Derpy. Pinkie pumped air into Derpy as hard as she could. Derpy's bell was getting bigger and bigger.
Derpy is now a little fat sphere shaped pony. Derpy was considering going bigger as Pinkie Pie was pumping air into her with a bicycle pump. Pinkie Pie pumped even more air into derpy. Making her even larger. She pumped even more air and made Derpy belly very very large. Derpy belly was the size of a house.
Pinkie Pie thought it would be really funny to go pony bowling with Derpy Hooves. So Pinkie Pie rolled Derpy Hooves all around town. Running people over with Derpy big belly. Pinkie Pie realized that the Ponyville Fair is coming up. So Pinkie Pie decided to enter Derpy as a freak show character. Pinkie Pie entered Derpy Hooves into the Freak Show.
The Next day. A crowd was standing by at the fair waiting to see "The Pony Balloon." They paid 2 bits to see Derpy Hooves. Everyone in the whole entire town decided to come out and see "The Pony Balloon".
"Presenting the one and only, Derpy the Pony Balloon." Pinkie Pie Announced.
the curtans open to reveal and inflated Derpy Hooves. Derpy Hooves cried because this wasn't a game to her. She felt exploited for being a fat balloon.
But then, Pinkie Pie wondered if she could pump Derpy Hoove's belly into the size of the moon. So pinkie Pie pumped air into Derpy to make her even Larger. Derpy was scared out of her mind as Pinkie Pie made her larger and Larger. Pumping every last breath into her from the Bicycle pump. But then the Bicycle pump broke. So Pinkie Pie got mad.
She decided to use a Air Tank to Inflate Derpy Hooves to the size of the moon. Derpy's belly got larger and larger and faster and faster. Until she got to size of the moon. Everyone in Ponyville got very scared and ran as far as they could in horror.
But Pinkie Pie on the other hand. Wants to make her larger. So Pinkie Pie inflated Derpy Hooves with an air tank on full speed. Derpy got larger and larger and larger until she pop.
Derpy than woke up. She looked at herself closely and realized that she wasn't a fat balloon. But that nightmare was too real for her to understand. So later on that day, she stole a bicycle air pump from Pinkie Pie and put the air pump in her mouth and inflated pinkie pie belly. Pinkie Pie got larger and larger while Derpy was pumping air into her. Pinkie Pie's belly was the size of a house.
Doctor Whooves got angry at Derpy and put the air pump into Derpy's mouth. Than Doctor Whoove's pumped air into Derpy mouth. Derpy Belly also decided to grow larger as Dr. Whooves was pumping more air into Derpy. Derpy Hooves and Pinkie Pie were about the same size for their bellies. Derpy and Pinkie Pie laughed at how huge they were. Because of the squeaky laughter, Derpy and Pinkie bellies started to shrink to their normal selves.
At the end of the day. Derpy and Pinkie Pie realized how fun it was to be big and a bouncy. They both had the most fun and Derpy realized how fun it is to inflate herself and that overcoming fears is a great thing. Both ponies were still friend unlike the dream and Derpy Hooves was the biggest pony in all of Ponyville. You see everypony, Its fun to blow up like a balloon sometimes. It really is fun to become that blueberry. Because at least you its fun when you want to be a big balloon. Everypony had a great time and they lived a happy life knowing that they can become balloons for as long as they liked. The End.
