When does Rubbadubbers return?

Seven anthropomorphic, friendly British bath toys called the Rubbadubbers live a peaceful life in the bathroom of a house somewhere in England. The toys belong to two children who live at the house named Benjie and Sis (however, they are never seen or heard by viewers) Every episode ends with the toys excitedly preparing themselves for their bath. The show focuses on seven friendly, sentient bath toys as they tell stories in imaginary worlds outside their bathroom.
