This mod is a bit unusual as it brings several characters at once in FNF game. All of them are from well-known Undertale. You remember the rules well – Boyfriend needs to outperform his opponents in rap battles. But it is too much challenge for the hero alone. And you will need to support the guy. Listen to new soundtracks and try to reproduce the rhythm by clicking the right arrows, enabling your character to dance to the music. Keep your mistakes to the minimum and win the contest with ease!
