A skeleton from Undertale cannot forget that Boyfriend could defeat him so easily in the previous FNF mod. Now he can think only about revenge. But this time, Sans will appear fully remastered, and you can hardly recognize him at first glance. However, there is no other solution but to accept the invitation to a rap battle. Be ready to help the guy as nine difficult songs await him in this new mod. So calm him down and coordinate all the moves to match the music rhythm as best as you can.
