Total Drama World Tour
Aliens are featured in the Area 51 challenge in The EX-Files. Two of them appear out of a box fallen off the roof of the room where Owen was given his clownish make-over. At first, the aliens appear friendly, but they cling themselves to Tyler and Alejandro's faces and begin electrocuting them. Duncan kills the alien attached to Tyler by punching it, and agrees to remove Alejandro's alien if he agrees not to vote him off during the elimination ceremony. They manage to capture the alien, after it gets off of Alejandro's face and electrocutes Owen, who is hypnotized to humiliate himself through Alejandro's talent of hypnosis. Team Chris Is Really Really Really Really Hot tries to bring the surviving alien to Chris, but Tyler, who is carrying the alien while Alejandro and Duncan carries the unconscious Owen, is too busy gloating about winning he forgets about the land-mines and one of them explodes on his feet, sending him flying to Chris and getting injured. The alien inside the box is killed due to impact of the fall. Team Amazon wins the challenge by bringing the alien's box to Chris, which happens when Courtney trips Gwen in an attempt to lose.

The aliens make another appearance in Aftermath Aftermayhem, when Blaineley brings them in as part of the "Total Drama World Tour second-chance challenge." In this episode they are referred to as Facehoggers. When it is Noah's turn, he lands on the Area 51 square and he is tasked to dodge high-speed lasers without moving off the square he is standing on. When Noah steps off the square because he is shocked by a laser, two aliens chase him back and forth and then latch onto his face as a penalty for losing the challenge.
