Montgomery the Goonie bird suffers from a chronic lack of confidence and simply cannot take to the air, although he tries to convince Doctor Dolittle it's more of a lack of interest. His chance to be a hero comes when the Doctor gets into a fix and Montgomery has to summon the animals to the rescue.
The doctor, his assistant Tommy Stubbins and his menagerie of animals (including the Pushmi-Pullyu) are sailing around in their ship, the Flounder, which is being chased by pirate Sam Scurvy. A turkey arrives to ask for their help. It seems that a giant boat race is taking place, and the winner will get Toots Turkey to eat for Thanksgiving. It's up to the doctor and his friends to save her, but Sam and his pirates have other ideas. They want to capture her to use as a hostage to get Dr. Dolittle to tell them the secret of talking to the animals.
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.
