FNF vs Mermaid Girlfriend (Seaside Serenade)


A mod of Friday Night Funkin that takes place in an alternative universe where Girlfriend is a Mermaid and met BF on the shore for a rhythm-battle.


A young, adventurous delinquent named “Boyfriend” was exploring the island jungles when he meets a beautiful mermaid named “Girlfriend” basking on a rock in a nearby beach. She invites him to serenade with her as their hearts beat in unison.
