Janitor Joe is a fox who is a janitor in most places of Busytown. Including the theatre, the school, etc.
In Richard Scarry's Best ABC Video Ever, after Ned's turn with the letter N, Ned forgets the flower is dying. So he opens the window and Joe floods Miss Honey's classroom. Janitor Joe is sorry, but he was just watering the flowers. Now he is watering the flowers, the children, and everything else. What a mess!
He is voiced by Ron Marshall.
