FNF with Ralsei (Friday Night Fluffin)


A mod of Friday Night Funkin where Ralsei rap-battle against different some other amazing characters.

Welcome to Friday Night Fluffin’, an alternate gaming universe where our lost singing hero, Ralsei, embarks on an adventure in a world he doesn’t belong. FIGHT alongside his soulmate, Isabelle, and discover the secrets this story has to offer, just don’t expect everyone you be to be quite what you think they are!

CHARACTER DISCLAIMER: In Friday Night Fluffin’s Universe, Ralsei and Isabelle’s age is one year apart from each other, I have to say this because some people love to make baseless assumptions without even bothering to check the lore once, with that out of the way, please enjoy! – Sourcy.


Include fun and upbeat songs.
