Part One: The Portal
F&J were battling Ice King like normal, trying to save Princess Bubblegum. Finn had used his golden sword to reflect Ice King's ice beam, knock IK out. PB was able to brake free of Ice King's arm, walking over to the two boys. "Thank you both for saving me AGAIN." She said. "I thinks it's about time we celebrate. Not with Richardo again, but this time, it will be amazing!" She said as Her and Finn were riding on top of Jake.
The two guys were preparing for the party they were invited for tonight. They were allowed to bring guests, so they invited BMO, Marcilene, Lumpy Space Princess, and Lady Rainicorn.
"Ah! I'm glad you could make it!" As Bubblegum invited them in. "Guys, you can enjoy the party. Finn, Jake, come with me!" F&J weren't sure, but without thinking twice, they both followed.
"I know you both love adventuring, so I thought you would enjoy seeing this!" as Bubblegum pointed to a strange machine. "Behold! The royal time machine!" She announced. "This time machine has been passed on by Bubblegum generations, and since I've taken the throne, it has been said only the chosen ones can handle it's power, I've put a lot of thinking into this, and I want you to have it." "But if it's being passed on by generation," Finn started. "You won't be able to pass this on to your children." Bubblegum gave him her look whenever she was about to correct him. "You see, the point of this time machine, is that the chosen ones are supposed to have it. No one in our family has found someone great enough, but now I know who I can give it to." Suddenly out of nowhere, LSP, Marcilene, and LR popped out. They all gasped in shock. They all ran over to see what it was, but accidentally pushed Themselves, plus PB, Finn, and Jake, all into the portal, sending them 5 years back in time.
