Steve visits Washington State University to join the New Breed Vets in the den of hibernating Grizzly Bears to unlock the secrets of their metabolism. The WSU has some of the most high-tech medical equipment which is put to the test on an American Bald Eagle and in San Francisco, Steve assists vets from the UK and the USA implanting an Elephant Seal with a microchip for first-time research on marine mammals. At Australia Zoo, Steve’s resident vet performs critical microsurgery on a Green Tree Frog to save its life, and in Singapore Steve helps a local vet administer Chinese medicine – acupuncture on a lame elephant.
