Yeah Fionna and cake live in the world of Aaa and Finn and make live in the world of Ooo.U know in the generic when we see Marceline?!Well we can see the mountains behind her,these mountains are the separation between the land of Ooo and the land of Aaa

Wtf ? Really ? 😳

Really? But I thought they were made up by the ice king? Aren't they just characters from his books?

Yeah I thought that too

What if ice king seen it all in the wiz realm and grown interest in those characters

Maybe Ice K saw them or something and now he is telling what he saw and just adding those parts where the girls love him.....I dunno....
