Fairy Tale (or the Adventures of Pirate Sally)
Rosie tells a story to the sick Snaggle, Sasha, & Rory.
Later, Tails nervously asks Fiona to the concert. However, to prevent Tails from potentially humiliating himself. Sonic decides to organize it so that everyone attends the concert together, Sonic tells Fiona that Tails has nothing but the utmost respect for her, but Fiona scornfully reminds Sonic that he left her in prison when he rescued Mighty and Ray. She divulges to him that her internal animosity towards the blue hedgehog has diminished once she has come to know him as truly heroic in the recent past. However, she still reminds him that he can still be selfish at times. Mina appears and is happy to see Sonic again. In an expected turn of events, this undoubtedly ignites jealously from Ash Mongoose. Nack makes his move and attempts to shoot Mina from deep within the throngs of attendees. Luckily for the Songoose, his plasma bolt hits a nearby tree instead. Bunnie kicks the tree into the lake to stop the fire from spreading and Sonic knocks out Nack before he escapes. Sally and Sonic force Nack to confess by threatening to have him united with Karl, Jeff, and Konor (his former gang) if he were to remain silent about his employer. Nack begins to tell them about how Dr. Eggman accidentally listened to Mina on the radio and was mortified to realize that this one particular song was the worst song he had ever heard. He thus had all Mina Mongoose memorabilia destroyed and jammed the airwaves in his territories to prevents his subjects from listening to her. Although, this did not work as expected. Dr. Eggman still couldn't get that one song out of his head. So he hired Nack to assassinate her live in concert. Sally assigns Sonic and the Freedom Fighters as personal bodyguard to Mina Mongoose to prevent another attempt. Doctor Eggman recognizes that Mina is still alive and switches to his contingency, namely Heavy and Bomb.
