The Garden Owner is an old man and the owner of the Garden of Betrayal. He appeared throughout Season Seventeen's Black Friday trilogy, consisting of "Black Friday", "A Song of Ass and Fire", and "Titties and Dragons".
The Garden Owner repeatedly shouts at Wizard Cartman from his house throughout the trilogy, as Cartman plots betrayal with Lady McCormick, Paladin Butters, Sir Kyle, Bill Gates, and Sir Stan in his garden. He laughs at Cartman when Bill Gates manages to turn Cartman's betrayal scheme on him and succeeds in informing Stan about the betrayal before Cartman successfully manipulates him. However, Cartman gets revenge on the Garden Owner for informing Stan by defecating in his garden, which he frames Stan for, getting him grounded.
The Garden Owner has gray hair and a wrinkled face. He wears a light blue collared shirt and a tan coat.
