Shout comes across the newest edition of the Mighty Music Band comic book. He calls the others, and they agree to meet at the Singing Pizza Café to read it together. Harper informs them that it is Mighty Music Band Day at the café, and asks if they would wear the costumes and serve the pizzas. The Fresh Beats oblige him. They suddenly hear a guitar rift, and head outside. Someone has frozen Melody, Reed, Harper, and other townspeople. After trying to unfreeze their friends on their own, the Fresh Beats run into the villain Deep Freeze (guest star Nikki Blonsky). Deep Freeze thinks that they are the real Mighty Music Band, and dares them to stop her. The Fresh Beats then learn that their costumes come with real superpowers.
