Tai and Joe wonder why these servants follow her orders, and they take them to their slumbering master, ShogunGekomon, who will only awaken after hearing a good singer. Mimi keeps them serving her otherwise she won't sing for them. After attempting to record Mimi's voice with help from, Tai, Joe, Agumon, Gomamon and Palmon are thrown in jail. After a bad dream, Sora comes out of hiding long enough to console Mimi. Mimi realizes what a fool she's been, and decides to sing for the Gekomon and Otamamon. Her crest glows as a result of her change of heart. When ShogunGekomon awakens to Mimi's singing, he is less than pleased and blasts everyone with the horns on his back.
