Somewhere in the world, there is a mysterious place called Jambo Island, because nobody’s gone in and nobody ever comes out. Only animals can go. A story about Jambo Island has been passed down through the ages from old timers to newcomers in the animal kingdom. Human could not learn about or find out Jambo Island, because they cannot understand animal language. Endangered or deserted animals have been gathered in Jambo Island to survive and they are making a new history in Jambo Island.

Meanwhile, aliens from outer space started to look for Jambo Island. They had been searching for Power Energy Flower in human world, but they could not find it. In human world, Power Energy Flower has been already extinct due to environmental pollution. Lately they knew the extinction of Power Energy Flower in human world and the existence of Jambo Island.
