chunk: His fortunes rise and fall again after a crocodile takes up residence, leading to his sister leaving in disgust with the intention of getting married, but his fame in the animal kingdom spreads throughout the world. He is conscripted into voyaging to Africa to cure a monkey epidemic just as he faces bankruptcy. He has to borrow supplies and a ship, and sails with a crew of his favourite animals, but is shipwrecked upon arriving to Africa. On the way to the monkey kingdom, his band is arrested by the king of Jolliginki, a victim of European exploitation who wants no white men traveling in his country.
  The band barely escapes by ruse, but makes it to the monkey kingdom where things are dire indeed as a result of the raging epidemic. He vaccinates the well monkeys and nurses the sick back to health. In appreciation, the monkeys find a pushmi-pullyu, a shy two-headed gazelle-unicorn cross, whose rarity may bring Dr. Dolittle money back home.
