S05E05 — The Lilo

The Trix return and the Winx are back at Alfea for training. Ms. Faragonda calls the Winx in and tells them about the Lilo, a magical plant which is on the verge of blooming for the first time in centuries, and it is somewhere on Earth, in Gardenia. Unfortunately, the Trix are searching for the Lilo as well to strengthen their own powers. The Winx find that the Lilo is in the possession of Macy, Mitzi's little sister. The Winx try to stop the Trix from gaining the Lilo and prevail with everyone believing in them once again, making their Believix powers stronger.
