Jane, David, and Greybeard set off to find out why hippos give birth away from their pods, while trying to reunite a baby hippo with her mom.

The trio head underground to dig into wombat defense tactics. Jane wants the community BBQ menu to explore new options.

David joins Jane on a high-flying mission to chart an albatross' journey instead of helping his sister Millie.

Jane convinces her reluctant abuela to help get a baby elephant back to his family, where she uncovers why herds follow a matriarch.

Jane and Greybeard lose hope when they see how humans impact chimpanzees in the wild, but David and a special friend restore her faith.
