Hi Sorry guys for taking too long In making a Fanfiction It's Cause I had a lot of things on my Mind and I barely had time to do this so I'm ending this , sorry guys but I already ran out of Ideas so the next chapter will be my last and It will be short cause I don't have that much Ideas , anyways I' am new to this so I hope you guys like it. If I made a few errors I apologize because this is my first time doing this and am not really good at this but if you guys like it.

I will be glad to get your opinion about my fanfiction and that's about it.

btw the characters are not mines, they're cartoon networks except water prince because he's my Original Character (OC) but the rest of the story is mine. Also the characters I'm doing it on are out of characters so the Fionna that I'm doing the story about I'm making her in a different way from her original version So I apologize If you guys think she's too girly It's because I made her like that so she's(OOC)anyways Oh btw I added two new characters but they're my own character that I made up they're names are : Grimm (Marshall Lee's Cousin he's half Soul Taker and Half Vampire he's the son Of the Grim Reaper and the son of Medusa the Snake Queen and one more her name Is Ashley ( Marshall Lee's Ex-Girlfriend ), Grimm , Ice Prince and Water Prince are my own characters except Ashely she's cartoon networks but I made her In a different way Just like Fionna , btw I decided to take 2 characters out of this story (James Flame Prince's brother) and Water Prince because I'm trying to end this story as soon as possible sorry for this okay and I hope you guys like this Fanfiction , anyways enjoy my fanfiction :
