Big sisters reign supreme in Disney’s Animal Kingdom! On the savanna, teenage African elephant Nadirah is a great babysitter for her little sister, Stella, but her skittishness remains a major growing pain. Animal care experts Erin and Elizabeth must get creative to help Nadirah face her fear and cross a bridge that connects two parts of the elephant habitat. At The Seas with Nemo & Friends at EPCOT, Harry, a rescued green sea turtle, must swim to a specific target for his leafy dinner -- a skill he needs in order to graduate to the main tank. At Gorilla Falls Exploration Trail, Alika, a little colobus monkey with a penchant for creating chaos, becomes a big sister -- a first for the park! Meanwhile, endangered vultures Carri and Bones try to fill their nest, but when the lovebirds can’t agree on the best way to build a home, animal keeper Tricia steps in to assist.
