In X-Treme Torture, Geoff and Leshawna receive the challenge of riding The Great Canadian Bucking Moose for their respectiveteams. Owen doesn't think he looks dangerous, and calls the moose "beautiful". But soon after, the moose hits Owen in the face with its front hoof. Geoff is almost immediately thrown off the moose and into a pile of smelly socks. Leshawna, however, manages to stay on the moose for five minutes, even after the moose breaks the fence and tramples over Chef, letting her team win that part of the challenge.
In Total Drama, Drama, Drama, Drama Island, Bridgette sees a small baby moose that is trying, but failing, to reach a branch. Geoff helps the moose, but Bridgette trips and accidentally pushes Geoff onto the moose, angering the moose's mother, which arrives seconds later. The moose chases Bridgette and Geoff down to the campgrounds, also pulling KatieandSadie into the chase along the way. The four of them manage to escape it by climbing up the ladder of a large diving board. They all barely escape, and Duncan arrives and asks what they're doing at the top of the ladder. They all point at the moose, which then turns around and attacks Duncan. It chases him into the main lodge, where Duncan manages to scares it away by taking an even larger moose head off of the fireplace mantle, holding it in front of him, and imitating moose sounds as he charges after it. Moments later, after Duncan lost his moose head and the moose outsmarts him, he is seen hanging onto its back as it gallops out of the woods. It runs right up to the Dock of Shame, where it then bucks him off of its back and into Lake Wawanakwa, resulting in his role on Total Drama Action.
In Crouching Courtney, Hidden Owen, the campers return to the island for their kung-fu challenge. During their training, Courtney piles a rock on Beth's back and stands on top of it while Beth does push-ups. To top Courtney, Duncan gets the moose onto Harold's back to also do push-ups so that he can feel the superior trainer. Duncan tells Harold to "be one with the pain".
In Aftermath: Bridgette Over Troubled Water, during a never-before-seen clip, Harold is seen talking to Noah about how in Alaska, it is illegal to talk to someone while they are moose hunting, when a moose suddenly charges at him, crushing him against a tree.
