Good morning! Look at the sun!
~ Jack Albertson's Grandpa Joe

Grandpa Joe is the tritagonist of Charlie and the Chocolate Factory by Roald Dahl and its film adaptations. He is first seen bedridden with Grandma Josephine, Grandpa George and Grandma Georgina at Charlie's house. Grandpa Joe tells Charlie that he used to work for Willy Wonka at the factory until Wonka tells his workers that his factory is closed. After the first four golden tickets were found by four bratty children named Augustus Gloop, Veruca Salt, Violet Beauregarde and Mike Teevee, Charlie has found the last Golden Ticket and Grandpa Joe decides to take him to the factory tour. During the tour, he and Charlie discover the chocolate room, a country-like edible room. After Augustus Gloop falls into the chocolate river and is sent to the fudge room, he, Charlie, Wonka and the other children enter the candy experiment room as Violet becomes a giant blueberry. After Vercua becomes a bad nut and is thrown into the garbage chute, Mike Teevee is shrunk after being zapped into television. Wonka tells Charlie that he has won and come to live with him to the factory, but will not allow his family to come with him too as Charlie refuses. After Charlie and Wonka visited Wonka's father, Dr. Wilbur Wonka, a dentist who now lives on the ends of the earth, Wonka reconciles with his father and Wonka allows, Charlie, Grandpa Joe and the entire family to move into his factory as Grandpa Joe helps Charlie and Willy Wonka begin to make new candy product lines at the end of the film.
