Life has settled back to normal in the old house and Becky and her mum are getting used to having Billy around, despite his strong odour. He even performs various household chores using his amazing strength! One day, Billy saves the cat from a screeching owl, who leaves an egg behind in his nest. When the egg hatches, it is up to Billy to reunite the baby owl with its mother and the resulting adventure is a crazy potion of fun for all ages, humour, thrills and chills.
