Audubon Woodlore, Dinah the Dachshund, Butch the Bulldog, Mortimer Mouse, José Carioca, and Clara Cluck appear as supporting or minor characters. Musical themes for each character were composed by Stephen James Taylor with a live 12-piece band and extensive use of the fretless guitar to which the music of the series was nominated for an Annie Award in both 1999 and 2001. Most of the shorts from the series were later used in House of Mouse.
