At Ponyville:
Pinkie said, tearing up, "Why did...you..li-lie to me about liking pies?"
Rainbow Dash said, "Well, I don't like pies and I was trying to not offend your feelings, also shouldn't you already know that I hate pie?" Pinkie said "Well, you never told me." then Pinkie ran away, Rainbow Dash set out her wings and started to fly to her house in Cloudsdale.
In Sugar cube Corner:
Pinkie Pie said, "Ugh, that Dashie, why does she always lie to me?"
Gummy blinked at her. Pinkie was making a pie. She poured milk into the bowl, then she said, "I wonder what a pony.."
She then shouts, "Ah Ha! Eureka, I have an idea, but I must depart at moonrise, or my master plan will fail."
she then clapped her hooves and said, "Dashie will be sorry!" she then walked to Twilight's house.
At Twilight's house:
She then knocked on the door and said, "Twilight let me in!"
Twilight said, "Oh hey Pinkie Pie, do you need anything, need a cookbook?"
Pinkie said, "Can you cast a cloud walking spell on me that will last a week?"
Twilight, perplexed asked, "Why do you need it for, you want to talk to Rainbow Dash about the fight you two had at Ponyville?"
Pinkie paused for a bit before saying, "Uh, yes!"
Twilight said, "Okay!" she pressed her horn and preformed the spell, she then said, "There you go, but you have till tommrow morning to use it or you won't be able to walk on clouds like the Pegasus."
Pinkie said, "Okie, dookie, loki!"
At Pinkie's house:
she then walked to her house to get the essentials from her secret chest. she said, "Let see, body bag check, knife, check, blueberries, check. Okie dookie loki, I got everything."
At Ponyville:
She then hopped outside of her house and pay 3 bits to use a Hot air balloon. She got in the Hot air balloon, and it went up and up and up. then it finally landed on a cloud, she is now in Cloudsdale.
At Cloudsdale:
she jumps out of the balloon and hide in a dumpster; she waits for nighttime so she can execute her true intentions.
she said, "It's 6PM, 2 more hours then I will execute: Operation Pie!"
2 hours later:
It is 8PM, Pinkie Pie jumped out of the dumpster and sneaked to Rainbow Dash's mansion. she then jumped very high and landed on the roof and jump down the chimney.
she's inside Rainbow Dash's house.
