A Nightmare on Freefonix Street

When Freefonix all have nightmares based on their fears, their Thirteenth Note powers begin to weaken. Vox sees this as a chance to escape the void by making Freefonix's nightmares come true: BB is near-invisible, Freez can't play his guitar, and Mo becomes tiny. Only a sound clash with Mantyz can restore the band to their former states.
