One day, Tails is walking by himself in Green Hill Zone, when two Trolls, Boyfriend and Girlfriend, emerge from the shadows, call him a talentless noob, and force him to rap.
After they beat him, Tails runs away crying, and tells Sonic and Shadow about what happened. Shadow tells him that he needs to stick up for himself and fight back, much to Sonic's chagrin. Sonic says that the Trolls are probably just misunderstood, so he heads back to Green Hill to attempt to have a civilized discussion with them.
While trying to reason, Sonic becomes disgusted, appalled, and angry as he realizes that the Trolls aren't willing to talk kindly, eventually losing his increasingly forced friendly demeanor and launching into the quickest and most brutal barrage of notes he can sing, but he still fails to defeat them. He gives up, and leaves, letting Shadow try his idea.
