The Black-Mud Swamp

As part of Professor Palladium's field trip, the class must navigate the Black-Mud Swamp to reach a clearing in the Gloomy-Wood Forest by listening to nature and without using any magic. The boys from Red Fountain are transporting a troll prisoner but the Trix cause their aircraft to crash land, and the troll is freed. The Winx and the Red Fountain boys end up meeting in the swamp, and must work together, despite their differences, to find their way out. They encounter the troll who is harassing some other Alfea fairies, and chase him off, however, the Trix find the troll and send him away. Although the Red Fountain boys failed to deliver the troll, they remark they are starting to feel like a team. The Winx girls, although they finished last in their assignment, are commended by their teachers for their helping others.
