The Flute of Rocklympus, while only appearing in the episode "Six Strings of Evil," was set to be a major antagonist of Grojband by Todd Kauffman prior to its quiet cancellation. According to lore created by Todd Kauffman, the Flute of Rocklympus, along with the Pink Star of Rocklympus, sought interest in Corey and Katrina Riffin, forcing their parents to put them in the care of their adoptive father Mr. Riffin. During the events of "Six Strings of Evil," the Flute of Rocklympus took on the form of a guitar, which then made use o Corey's naivety to possess him.
