In Ponyville, ponies all over town were ditching parties because of their problems. Pinkie Pie was determined to stop this. She loved parties, and she was going to make the other ponies do too. She called all her friends and told them, "Plan parties all over town. Make sure people never leave the party unhappy!"
Her friends reluctantly did it. Pinkie Pie set up at Sugarcube Corner, Applejack at Sweet Apple Acres, Twilight in front of the library, Rarity in her shop, and, of course, Rainbow Dash and Fluttershy on the clouds.
They all finally got the party poopers to be happy! Pinkie Pie and her friends were so happy too! Mostlly her friends because they didn't want to do it in the first place. Everyone was almost always happy from that moment on.
