Popstars!.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. Though their concert is interrupted by Obscurum's attack on the core of Peripla. The Winx transform into their Cosmix form and go battle Obscurum, though they are too late, and the core of Peripla is drained. The Winx use their Cosmix powers to restore the core successfully. Then though, Valtor creates a black hole, in which he intends to suck the specialists' spaceship & Peripla into.
