Doctor Dolittle

The Barnyard Rumble (1x13)

:

Dr. Dolittle and his crew go to a farm filled with many talking animals to help a rooster who can't sing "cock-a-doodle-do" in the mornings because he lost his voice. The Pirates, disguised as a motorcycle gang, raid the farm. Check out the cool 1970 biker gang outfits and the even cooler 1970 motorcycles that they're driving.
