A long time ago humans left the planet Earth. Alone remained Lobo. Lobo is a cheerful robot who loves animals and plants. Lobo’s biggest dream is to live in a flourishing forest with his best friend Banjo, a curious robot dog. Together, they help to plant trees and rescue animals in need. One day they meet a stranded whale on the beach. To save the whale Lobo has to overcome his fear of water, but it’s not easy especially when a single drop of water can make him rust.
