From the publisher:
Back from Africa, the Doctor is short of money as always. So he takes the pushmi-pullyu on tour in Doctor Dolittle's Circus. But in Albert Blossom's circus, what he finds is a whole new family of animals in need of his help.
In Doctor Dolittle's Caravan he expands his circus to include the grand "Canary Opera," and makes a sensation of its star, Pippinella.
And in Doctor Dolittle and the Green Canary, Pippinella tells her story to Doctor Dolittle in her own words.
