During their quest to stop Balthazar the Fabulous from sucking every last sunbeam out of the sky, the heroes realise there is something wrong with Hoofius, who keeps tripping up and has totally lost his confidence. Herbert explains that Hoofius has lost his mojo! To help their friend and complete the quest, the heroes take Hoofius up Mojo Mountain to help him get his mojo back.

The heroes are excited to visit Whizzpop's Pop-Up Bakery and taste his magical cakes, but they are shocked to find that the protein bars have shouty raisins in them, the custard tarts are rock hard, and the floating sponges keep floating away! Trevor quests to solve the mystery, but having accidentally fallen into Whizzpop's invisibility flour, how on earth will he get everyone's attention?

When Stinkweasel drops a rain of yukkiness onto the forest, the Fairy Squad, with their excellent flying skills, decide they are the ones for the job. However, Hoofius insists this should be their quest, even if he does hate ick! And when the Fairy Squad get their wings gunked and are unable to fly, the heroes can resume their quest to end Stinkweasel's reign of stinky nonsense - no flying required.
