Postman Pat: Special Delivery Service S02 E16 Postman Pat and the Didgeridoo

Pat is delivering two things - Dottie the hamster and a didgeridoo from Australia - both to the school. But when Dottie goes missing and everyone is searching high and low for her, it's the wibbly-wobbly music of Pat playing the didgeridoo which helps to uncover her hiding place in the end!
