Arthur Crandall was a short-lived, though enormously successful, children's entertainer in Springfield.
Arthur Crandall was the ventriloquist behind Gabbo. He was the one who used him in the shows. It was thanks to his and Gabbo's enormous popularity that got Krusty the Clown cancelled. After Gabbo is found out to of used foul language and Krusty comes back in a comeback special, Arthur and Gabbo go down-hill and are soon forgotten.
Arthur Crandall and Gabbo were inside the dome during Trappuccino.
