The series was inspired by Hirsch's own childhood experiences and his relationship with his own twin sister growing up during their summer vacations. He placed many of his real-life experiences in the show, like living in Piedmont and trick-or-treating with his sister as kids. Dipper Pines is based on Hirsch's memory of how it felt to be a kid. When Hirsch was around Dipper's age, he "would record [him]self and play it backwards and try to learn to speak backwards. " Hirsch described himself as "that neurotic kid who would carry 16 disposable cameras everywhere I went. " Mabel Pines was inspired by his twin sister, Ariel Hirsch. According to Hirsch, just like Mabel, his sister "really did wear wacky sweaters and have a different ridiculous crush, every week. " In the series Mabel gets a pet pig, just like his sister had always wanted when she was a kid. Grunkle Stan was inspired by Hirsch's grandpa Stan, who according to Hirsch "was a guy that told tall tales and would frequently mess with us to get a rise out of us. So, my family really inspired the characters on the show. "
