Nature's Strangest Oddballs (1970)

Professor Ludwig von Drake narrates live action footage and animation about the planet's more unusual animals. Films show the iguanas of the Galapagos Islands and Australia's lungfish, duck-billed platypus, kangaroos and koalas. Cartoons include the story of a cold-blooded penguin and a flying burro (both from The Three Caballeros) and of Goliath II, a pint-sized elephant.
