Inherit the Earth

Red is an ape that becomes separated from his father. He is terrified that a wild animal has attacked him. But as he makes his way through the woods, he stumbles upon something far stranger; an animal community hidden in the forest. He is welcomed with open arms by all sorts of animals he has never seen or heard of in his life. As they make him a part of their society, he learns the great truth.
The Humans are gone.
It's time for the animals to inherit the Earth.
