Grandpa Joe is the father of Charlie Bucket's mother and the tritagonist of the film.
Grandpa Joe used to work for Willy Wonka from the simple small candy store on Cherry Street to Willy Wonka's famous chocolate factory.
Grandpa Joe was fired with the rest of the other employees after spies had stolen Wonka's secret recipes.
Grandpa Joe is delighted when Charlie finds the last golden ticket enabling five lucky young kids and their guardians to explore the Factory. Sadly, he and Charlie got sucked into a exhaust fan.
