The series aims to encourage young children to learn about the world around them. The starting point for each programme is something with which children are already familiar, such as water, wood, paper, boots, spiders, buses, soap, street lamps. The two main characters are Auntie Mabel (played by Lynda Baron of Open All Hours), and her dog Pippin.
They go on adventures in Auntie Mabel's aeroplane, travelling far and wide across the UK to find out more. Music, rhymes and stories enrich the programme topics.
