Gino, the most admired western lowland gorilla at Disney’s Animal Kingdom, celebrates his 39th birthday with animal manager Rachel, who’s known Gino since he was a teen. Gino’s presented with a storybook-worthy cake, but festivities are stalled when he struggles to overcome a chest infection. Meanwhile, animal keeper Lori notices a lump on beloved alpha lioness Kinsey, which requires urgent medical attention, but transporting the 300-pound cat to the Veterinary Treatment Room poses a challenge. At Discovery Island, trainer Katelyn teaches two newly arrived macaws, Santiago and Emmett, the navigation skills needed to become members of the Winged Encounters flight team.

For the first time in the park’s history, Hartmann’s mountain zebras arrive on the savanna at Disney’s Animal Kingdom! Keeper Meaghan and the team do their best to acclimate the mischievous herd and prepare the other animals to meet their new neighbors, including a curious young Hartmann’s mountain zebra, Clementine, and mom-to-be Prima. Meanwhile, babirusa pig Betty is introduced to a bachelor babirusa, Mentari, with the hope that the plucky pigs hit it off and give the park its first-ever babirusa piglet.
