Saving nature, what an adventure!
In a war-scorched world, the Earth's inhabitants have taken refuge underground. 24 Bio robots called Chumballs have been dispatched to the surface, armed with the ability to detect signs of life and then signal below ground to the human beings. Three children and their little robot Tago have been sent to the surface to find the Chumballs, reactivate them and try to free humans from captivity.
