I've been thinking lately, if there were to be a movie about AT, should it be able to include Fionna and all the genderswap characters?

How would you react if there was an Advneture Time movie and you saw that the genderswap characters were not just from Ice King's imagination, but they were also from another continent nearby the land of Ooo?

I wanna hear what would happen in the movie, and i want it as realistic as possible please!

Should there be suspense? Romance? Happy Ending?

And last but not least, should PB return to being 13 in the movie?

I want to hear ideas and what would most likely happen.

Thanks! =D
