Winx Club Forever
The Winx need to find another clue to find the Gem of Self-Confidence, so they traveled Andros' ocean to find the Shimmering Shells in the Labyrinth of Abysses. When they arrive, it is seen that Tritannus had spread pollution, and the Shimmering Shells were releasing pollution and making illusions. However, the Winx manage to purify it again. After that, the clams give the Winx a new clue.
