A/N:This is my first published fanfic! So excited! Anyways I do not own Adventure Time, Pendleton Ward does even though the idea for this story is mine and whatevs :p

Finn's POV

It was a normal day, being math, beating up the Ice King for being a total idiot and Marceline came over.

Me and Jake played with Marceline and Bubblegum no matter how hard she resisted arguing at Marceline how her tempo was off. Perfectly normal... until some wierd girl with a white bunny hat and some dude with a plaid shirt crashed through the window. Just a bit later some ice lady came to try to destroy them. The lady said "He will be mine!". Then the girl and the ice woman started fighting. It was about a Gumball prince? This seems too familiar... Pretty soon I had enough of all this, so I said (more like yelled) (Get out of my head Jake!) (HeHeHe) "Who are you and what are you doing in my tree house fighting about some Gumball prince? And who's this dude just doing nothing!"

Fionna's POV

After that boy said that I yelled at the top of my lungs (which is louder than how I yelled when Marshall decided to place catnip in my hat and Cake was all over me for DAYS."Ice Queen here tried to steal Prince Gumball and forcefully marry her! What kind of sick person would do that? And she thought it was "his and her destiny" which makes no sense I mean seriously!". Then after I said that the boy, his yellow dog, a floating girl and a pink girl had their jaws to the floor. How does this seem familiar? "Also what are you doing in my house with your friends! You better get out!

Finn's POV

"Your house? You are in my house and what are you doing with my style of hat? Also...". Then I thought of something. Is she a human?

Fionna's POV

"Is he a human? So i'm not the only human left?". Then I stared at Marshall though dreamily seriously and pointed to the boy and mouthed "I thought I was the last human?"

Marshall"s POV

After she mouthed me that I nodded and floated over to the boy and his friends and said " Whydo all of you look like me,Fionna,Bubba, and Cake?

Marceline's POV

The moment he said that I noticed something... the all were us but different genders. So then I went to Finn's ear and whispered "They are us.". Suddenly confusion was all over his face and you could tell.
