Synopsis
Tai, Joe, and  take Matt's swan boat to a large castle on an island. 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.

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, and has all five of them thrown in the castle dungeon.

After having a bad dream, 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. He is eventually defeated by, and Mimi joins Tai and Joe as they set off to join the rest of the group.
