It had been a month since Mabel and Dipper had been sucked into a portal and taken to a place called Ponyville and turned into ponies. But the twins had almost forgot about it, and they actually were really happy for summer break in Gravity Falls. Life was good and they were turning 13 soon. They would finally be teenagers! Dipper and Mabel have waited all their lives for that day to come, obviously for different reasons. Dipper, so he could brag about it and Mabel so she could be proud (Well it got way more specific, but...we don't need to know that!) Mabel and Dipper had it planned out, it would be an epicly awesome twin party with tons of people. Half of the huge room would be a girly, sparkle pink party where only girls are allowed and the other half a cool hang out party where only boys are allowed. They were super excited and in all of Dippers brain, that was it. But in back of Dippers mind, the Ponyville memories haunt him. But all of that changed when the day before the big day, the Mane 6 were working on a spell when a familiar portal popped up before them and sucked up all 6 of them.
