A singer named Catty Carlisle is invited to the REBL studios by Mad Dog Max. Catty starts singing a song in a Texas style as she dedicates it to "Mobius's number one hero, Sonic".
Meanwhile, Scratch and Grounder are on a mission to capture Sonic by using a bear trap. As the two get distracted by a radio playing 'Sonic's Song', Sonic comes and makes fools of them and they get trapped instead. Scratch and Grounder go back to Robotnik and he gets upset that Catty is singing a song about Sonic. So Scratch and Grounder head to REBL studios and try to capture Catty but Sonic dresses as an interviewer and distracts the two by saying that they have just become instant stars on radio. As that happens, Robotnik decides on another plan by making only one song in the whole of Mobius that is Robotnik's anthem, so he creates the Music Destroyer (M.D.) to put an end to all other music. After he captures Catty, Sonic and Tails try to save her but end up being captured themselves. Sonic manages to trick Scratch and Grounder into freeing them and plays very loud rock music to destroy the M.D. Sonic returns Catty's guitar and she walks into the sunset with Sonic and Tails, singing Sonic's song.
Sonic's Song that Catty wrote is the show's theme music with added lyrics.
When Sonic and Tails go into the room with all the stolen instruments, Sonic picks up a guitar and poses with it and says "Check out my Eddie Van Hedgehog Impression" which is a reference to Eddie Van Halen of the band, Van Halen.
