Written İn The Stars.The Winx reach Valtor's palace to try to defeat it and take the other prime stars. The group attacks the castle attracting the Trix to the outside and, while Bloom, Musa and Tecna face them, Stella, Aisha and Flora take on the appearance of the three witches to try to catch the stars; however, as they try to deceive Valtor, the real Trix return, forcing the Winx to fight against the wizard, who has turned into a gigantic demon monster. After hearing from Bloom that Valtor intends to destroy the Magic Dimension, Icy does not know who to give the prime star in his possession, but in the end he delivers it to the Winx in order to be able, one day, to save Dyamond and her sister. Since the Winx now have four stars out of seven, the stars imprisoned by Valtor are freed and converge in the Star Case, freeing the Wishing Star. To have brought together the prime stars, the Wishing Star gives the fairies a wish: after thinking carefully about it, Bloom asks to protect the magical universe, safeguarding its harmony forever. Once expressed the desire, the Winx receive a charge of energy and manage to defeat Valtor, while the Trix leave. Once returned to Alfea, the girls organize a concert and, out of gratitude, a new constellation appears in the sky: the Winx constellation.
