In this CYOA, the player typically assumes the role of a protagonist who has been captured or finds themselves in the service of a goblin hierarchy. Unlike standard power-fantasy games where the player is an unstoppable hero, this title focuses on the nuances of survival, influence, and adaptation within a subterranean society. The "Pet" subtitle refers to the protagonist's initial status, forcing players to use their wits and social maneuvers to climb the social ladder or find a way to escape.
