This is a FANFICTION of Adventure Time.
Fionna, Cake, Gumball, Marshall, together with the stalking Ice Queen take an adventure outside the Land of Aaa. They will soon cross over to the Land of Ooo. What happens if they meet particular people like Finn, Jake, Bubblegum, Marceline and the Ice King? What could happen?
Disclaimer: I absolutely DO NOT own Adventure Time. This is just a FANFICTION. Plus, if I did own it, the Land of Ooo and Aaa would not be separate lands.
