As part of Professor Palladium's field trip to Black-Mud Swamp, the class must navigate from Black-Mud Swamp to the clearing in the Gloomy-Wood Forest by listening to nature and without using any magic. Unfortunately, the trip doesn't start well as Stella struggles with the wilderness and Tecna is tempted to use magic within minutes to escape a mud bog. While the girls find their way to the school, the boys from Redfountain have been assigned to escort the fugitive troll captured in Gardenia to Magix city for trial. Unable to let their plans come into the open, the Trix plot to rescue the troll and then destroy him along with their secrets. While flying over the swamp, the boys' ship is shot down, forcing them to crash land and allow the troll to escape. As the Winx continue back to Alfea, Flora and Bloom begin to use nature to guide them, leading them to the Specialists who have been caught by vicious plants. After Flora helps them escape, the two groups team up to find the troll. While following the voice of nature, the gang finds the troll attacking another group of Alfea fairies! The Specialists rush in to tame the beast, but their bickering allows for the troll to run off again. As the groups continue to bond with each other, the boys overcome their arguing, only to follow the tracks to a dead end. Sadly, the Trix reach the troll first and send him to oblivion. With their respective assignments ending in failure, the boys head back to Redfountain while the Winx are the last to reach Alfea. But the missions still turn out well as Timmy states for the first time he felt like a part of a real team while the Winx receive top marks for acting like real fairies; using wit to solve problems and always being willing to help.
