When Maya, Connor, Lily, and Franky discover that music is mysteriously disappearing from both Wobbleton and the game world, they must race to the Harmony Hills to protect the last remaining Song Well. But their enemies this time work as a perfect team: Mute Button steals all sound, while Cacophony creates chaos with too much noise.
Can the Pixel Players find a way to restore harmony before both worlds lose music forever? And what happens when their real-world parents start to notice that something truly magical is happening to their children?
