Friday Night Funkin' - Vs Penny Crygor Full Week

Boyfriend and Girlfriend find themselves in Diamond City, somehow...
Clearly something, or someone, was after them so they found a weird-looking place and decided to hide in the vents. It turns out that they had wandered into Penny's Lab right as she was finishing her latest invention, The Melodic Microphone Mk V. BF and GF then fall out of the vents through a little doorway in the same room Penny was in. BF then notices the mic Penny was holding and decided to challenge her to a rap battle. Penny was gonna test out her new microphone anyway so she accepted BF's challenge. Unknown to BF & GF, Penny can sing ANYTHING!
