The Winx have lost all their magic as punishment for sneaking into Cloudtower, but to make matters worse, Griselda tasks them with cleaning the entire school without their magic (or technology, much to Tecna's dismay) while the rest of the students and faculty go to a concert. Problems continue as Tecna struggles with no gadgets to help her, causing her to wear a bucket on her head and attempt to use a broom, while Musa, Stella and Bloom have a water fight, wasting their time, energy and supplies. In order to make the punishment lighter, the girls secretly invite the boys from Redfountain over after everyone has left, claiming to be throwing an all-night party. Meanwhile, the Trix use the opportunity to sneak into a near-empty Alfea to find the real fuente of the Dragon Flame. The boys arrive and instead learn they'll be working as janitors, though they still play música as they work. Soon after, the Trix teleport to Alfea and summon the vacuums to guide them towards the Dragon Flame, while distracting the gang por summoning a monster. The Winx and specialists quickly meet their distraction, and while the boys try to fight with their weapons, their quickly knocked aside. The Winx, despite having no magic, manage to outsmart the beast por using floor cleaner. Unable to find the Dragon Flame, the Trix depart to Cloudtower, unseen por anyone while the Specialists head back to Redfountain. The siguiente morning, Faragonda sees the damage and hears the story from the Winx and as a reward for defeating an adversary using only wits and resourcefulness, the Winx's powers are restored.
