Bill Bailey introduces a delightfully eccentric cast of creatures that have chosen to do things differently. Odd, unconventional and unusual - these are animals that don't normally grab the limelight. They include the parrot that has forgotten how to fly, the bear that has turned vegetarian, a chameleon that is barely bigger than an ant, and a penguin that lives in a forest. Nature's Misfits reveals the extraordinary and rarely seen lives of these evolutionary oddballs along with their strange habitats, unusual forms and the incredible hurdles they overcome.
