S1, E6: Jessica and Gina have enlisted the help of Nick, Toby and Lucas in their new dog-walking business. Business is booming, but when wild animals escape from the zoo, the kids learn from Razzle that big things are going down in Gorm, rumours that The Ancient Guardians have returned to Gorm. Jessica plays Keeper as the kids check out the Gorm Forest where they discover the large, majestic creature Troncalion, the ancient Forest Guardian! The rumours were true! Troncalion is in a trap laid by Magmion! The kids manage to free the Forest Guardian, but just then Magmion arrives flying his own ancient dragon steed, Guardian of Fire, Drakkon! Magmion slaps a control collar on Troncalion and spirits him away. During the battle, both Lucas and Nick run out of glow and transform back into kids, so it's up to Lord of the Water, Toby, to track down Magmion. Meanwhile, the boys go back to Venture Falls where they assist Gina, who has become an overwhelmed dog-walking-business-of-one! But while the boys help wrangle her runaway dogs, they run into one of the zoo's escaped lions! Fortunately, one of the dogs starts barking, the others follow, which scares the lion away. Back in Gorm, Toby has tracked Magmion to the shore where he has enslaved the ancient guardian of the sea, Tentaclion. Nick and Lucas return to Gorm, but it's too late to help Tentaclion. Now if Magmion can collar the Earth Ancient, Roscalion, Magmion can channel the powers of the Ancients to open a gateway back into Venture Falls and strike at the very home of our heroes. With only enough power to destroy one collar, our heroes target the collar on Drakkon, realising that it is the evil master control collar that 'leads the pack' and enslaves the good Ancients. With Drakkon's evil control collar destroyed, Magmion's plot is foiled and the good Ancients are free once again, only now they have bonded with their new friends, the Lords of Nature!
