The family is reimagined as animals in a nature mockumentary. Narrated in the style of National Geographic, the episode follows Homer and Marge as whales from different species drawn together by instinct, Bart as a newly hatched iguana fighting to survive against relentless predators, and Lisa as a finch leading her flock toward innovation. As each character faces the challenges of the natural world, familiar faces from Springfield appear in unexpected ways, bringing a fresh perspective to the struggle for survival in the wild.
