Welcome to the boggling and beautiful world of Moody Beasts. Why does a bull moose cover himself in his own urine? Why would a clownfish change his sex on cue? How can a marsupial mouse push himself to have sex until he dies? All creatures, including humans, are consumed by the answer. It’s the mysterious and powerful chemical cocktail that is the rocket fuel of life—hormones. Now with three spirited one-hour specials, this light-hearted and playful series explores the secret, primal force that drives the animal kingdom to extreme behaviours.
