In the spring, there are many babies: Émilie prepares the meal for the orphaned bears. For his part, Cliff is working on the most ambitious project in the zoo's history: a new enclosure for Kodiak bears. Lloyd also celebrates his party on the construction site.

Still in Thailand, Cliff, Émilie and Lloyd visit the largest refuge in the country. They have the chance to visit this center where hundreds of animals of several species are saved, including macaques retired from coconut picking.
