Upon entering, they find lots of and  rushing around, running various errands for the "princess", who turns out to be none other than Mimi. When Tai and Joe tell her she has to go, she reacts badly and has them all thrown out by her servant Digimon.

Tai and Joe wonder why these servants follow Mimi's orders, and they take the group to their slumbering master,, who they say fell into a deep sleep after losing a singing contest, and will only awaken after hearing singer as good as the one that defeated him. They explain how told them about Mimi's amazing singing voice, so they found her and had her sing for them. The first time, Mimi forgets the lyrics, so the Gekomon and Otamamon serve her a food buffet to help her remember. The second time, she complains about the lack of decoration and asks for a makeover. She continues to make excuses and demand things from the Gekomon and Otamamon, becoming spoiled and eventually not singing at all, even threatening to be unable to sing if her demands were not met.

Tai's first suggestion is that he sing instead of Mimi, and everyone in the group ends up having a go, all failing miserably. Tai's next plan is to record Mimi's singing on tape, with 's help, though Mimi quickly finds out, reveals she's on to the deception, and has all five of them thrown in jail as punishment.

After having a bad dream where she is attacked by Devimon and Etemon, and everyone, including Tai, Joe, their Digimon, Palmon, and the Gekomon and Otamamon, abandon her because of her selfishness, Mimi wakes to sees Sora, who comes out of hiding long enough to console Mimi. Mimi realizes what a fool she's been, and her crest glows as a result of her change of heart. She releases the group from jail and decides to sing again for the Gekomon and Otamamon, much to their pleasure. When ShogunGekomon finally awakens to Mimi's singing, he is less than pleased at being disturbed, and blasts everyone with the horns on his back with his Musical Fist attack.
