Odd how one looks like a grape and the other a blueberry

I just thought out a plot for this pic. ahem
 
Rainbow Dash opens the door at Sugarcube Corner and sees her best friend Pinkie Pie. “Oh! Hiya Dashie!” Pinkie says as soon she opens the door. “Oh, hey Pinkie.” RD said back. Then, Pinkie shows Rainbow a piece of gum she had. “What’s that?” RD said confusingly. “A friend of mine gave this too me, it’s apparently some magic gum!” Pinkie had a big smile on her face while saying it. “I… wouldn’t eat that if I were you…” Rainbow was nervous. She had no idea what this gum was. After a blink, it was gone and into the pink pony’s mouth. “Awww mare!” Pinkie said disappointedly. Rainbow, now realizing it was not that bad, Ate some herself. As soon as she chewed it, Rainbow saw something on Ponk’s nose. “Hey, Pinkie you got som- OH SWEET CELESTIA” The rainbow pony now realized it does work, but it was too late. After a minute, the pink pony was now all blue. Rainbow saw her stomach swell. “Oh, hehe! This should be fun!” Pinkie was enjoying this strange effect, somehow. Soon after Rainbow started swelling up, as well. Her hair was now all Purple and Blue. “What’s happening to me?” Rainbow asked scaredly. The swelling got bigger and bigger. The two ponies were now a deep shade of blue. Their tummies were swelled up. Juice was now flowing. Rainbow was so embarrassed. Pinkie touched Rainbow’s juicy stomach. “Look at that big tummy, Dash!” Juice spitted out Ponk’s mouth. Pinkie also have it a little tap. She grinned and hugged RD tight. Finally, the swelling stopped. The two ponies were now just a giant ball, a blueberry, if you will. They were now even at a deeper shade of blue. The juice felt so nice to Pinkie. RD though, she wanted no part in this. 30 minutes have passed and they were back to their normal selves. “Lets NEVER do that again!” RD said. “Okie Dokie!” Said the pink horse. RD left while Pinkie ate another one. The end. Hope you enjoyed!
