In the sweet land of Waffle Island, the Jellies are living a peaceful life of harmony and sweetness. To the rhythm of their mystical Rhythmophone, our heroes are going on with their day-to-day activities, using their unique powers to create and entertain.

However, jealous with the Jellies music, the evil Sourbots have invaded Waffle Island and have stolen the Rhythmophone.

A team of brave Jellies (Jawbreaker, Punch, Licorice, Gummer and Honey) have decided to embark on a perilous journey to retrieve the Rhythmophone. Their quest will take them from the dark (and delicious) canyons of Chocolate Island, to the looming peaks of the BonBon Mountains and through the dangerous Frostie Wastes, to the World Cherry, growing on the top of the world.
