Okay, one day Finn and Jake wake up and everthing is fake such as their bed,walls,ext. and the're wearing halloween costumes then suddenly all the stuff falls down and they relized they aren't in ooo any more but in aaa so when they fall the land into fionna and cake's house and the they go on an adventure and find marshel lee so then marshel lee takes them to the nightospere and find the gender swapped version of hudson abadeer.
I haven't thought about the rest
It is not likely to happen
