|When Troy agreed to move into Pierce's mansion at the end of his first year at Greendale ("Pascal's Triangle Revisited"), he had no idea the horrors that would await him. Every night he had to look into the face of terror in the form of a Norwegian Troll Doll before he went to sleep. After Pierces falling out with the group ("For A Few Paintballs More"), Troy left the mansion soon afterwards. At the start of the following semester moved into an apartment with Abed. He tried to forget his time at the Hawthorne Manor but Pierce had a plan to make him remember: he brought a special gift to the duo's housewarming party. The Norwegian troll doll's first appearance was in the Season Three episode "Remedial Chaos Theory."|
|When Troy moved in with Pierce in before his second year at Greendale, he was disturbed by a Norwegian Troll Doll that was on display in front of his room. He would later claimed that it watched him while he slept. Pierce knew he hated the doll and brought it with him to a housewarming party for Troy and Abed]]'s new apartment. He wrapped it up and intended to give the troll doll to Troy as a house warming present to mess with him. In the various scenarios imagined by Abed, Troy freaks out whenever he sees it. In the darkest timeline, Troy tried to swallow the troll doll whole while it was on fire and ends up severely damaging his throat. In the actual "prime" timeline, Pierce is enjoying himself at the party and decides not to give the gift to Troy, throwing it in the garbage instead. ("Remedial Chaos Theory").
|In the study group's senior year at school, Pierce accidentally locks himself in his mansions panic room. The study group forgoes a Halloween party to rescue him and splits into groups to find the codes to unlock the door to the panic room. While in the library, Abed finds a bookshelf decorated with Norwegian Troll dolls. A doll named "Torg" appears to be missing from the collection (presumably it's the one Pierce had intended to give to Troy). Abed pulls on a doll named "Grot" and discovers it's a switch that opens up the bookshelf and reveals a secret room that has monitors to all the surveillance equipment inside the mansion ("Paranormal Parentage").
