"We ran into her while we were out hunting for Gumball. She was frantic, fascinated and got a bit fresh with me. She told us her world was called Ooo, just like ours...but in her world a boy named Finn saved the day and the Queen of the Vampires was named Marceline. I thought she was crazy...but as Fionna lead her back to her Tree Fort we began to notice the world around us shifting...changing. Slowly our friends began to disappear, swallowed by the paradox of Bubblegum's presence. It's only us three now; continuing on with Fionna's sword, Bubblegum's sciencey know-how and my rugged good looks and chill beats.
Somehow, we'll set things right....before it's too late."
