Twelve Angry Animals (S06E09)

The Planeteers are scaling Mount Everest in the Himalayas when they chase after a snow leopard and tumble into a hidden cavern. Inside, they meet a Yeti and a group of 12 talking animals that are either extinct or endangered. These creatures begin to assess not just the Planeteers but humanity as a whole. They transport the group back to the Ice Age and other historical eras, revealing how humans have hunted them or destroyed their habitats, leading to their decline. This episode serves as a lesson about the delicate balance of nature, illustrating how we can possess everything one day and lose it all the next.
