Chapter 1:
Princess Bubblegum was in her laboratory thinking of a new invention to create for her annual science barbecue, it had not been as successful since the time Finn created a black hole right in front of them. She had been up for almost 18 hours straight trying to think of a way to make her time machine work the same way Simon's did and failed miserably. She was almost out of ideas when suddenly a thought came to her: "I could try to create a portal to another dimension! Almost like the one Finn's dad disappeared through!" She had only a few hours to get it done before it was time for her to make preparations for the barbecue. She worked for hours on end, but she realized the reaction needed to create the portal would take too long and the barbecue was in 9 hours. She, without thinking it through, added a catalyst to speed up the reaction. She calculated that time reaction time would be divided in half so she went to take a short nap and by the time she woke it would be nearly complete!
She woke up to the sounds of chaos throughout the kingdom, she was dazed and immediately ran to her laboratory only to find that the portal had been opened or hours and was consequently unstable. She knew that it had already started created ripples in space and time, she ran outside to her balcony only to find that her kingdom was slowly imploding as if it were a star at the end of its life cycle. Everything was quickly closing in and the ripples of space and time were causing havoc. She knew she had to stop the reaction from the source, so she ran back to her lab to try and stop the instability from reaching its climax, other wise all of Ooo would be sucked into the portals. The portal was blowing hurricane force winds into her lab, scattering her papers and chemicals everywhere. She managed to find the precise ingredients she needed among the mess of broken glass, torn books, and lab equipment. She made the serum quickly and added it to her brew and suddenly the portal closed shut and the chaos that came with it subdued. Bubblegum felt something grab her leg and she shrieked: "Eeeeeekkkkk!" She went to run but fell flat on her face because of whatever or whoever was clutching tightly on to her ankle; when she looked back she saw Marceline, but with shorter hair... and a less curvaceous body. Bubblegum sat up to see if it really was Marceline, so she picked up the person's head and suddenly she knew; it was definitely NOT Marceline.
