Roobarb is a green dog, and Custard is a pink cat. Roobarb is always involved in some kind of misadventure, and Custard continuously attempts to sabotage him. Despite his frequent failures, Roobarb possesses undepleted enthusiasm and a wild imagination. Intentionally animated in a rough style, which gives it an energetic quality, the cartoon was an iconic part of 1970s Britain.
