At Alfea, Sky is preparing a romantic picnic under the stars for Bloom. But his surprise gets destroyed when the Winx have to leave for a new mission: they will need to save Peripla, a star-ship, from Obscurum and the staryummies. In order not to expose themselves to the lumens of Peripla, Twinkly comes up with the idea of the Winx posing as intergalactic pop stars. The Winx arrive on Peripla, and start a concert in honor of the Peripla lumens.
