The Mould Busters

George and his friends are playing their favourite video game – The Mould Busters. After another successful round, they decide to celebrate by eating a special sandwich: a sandwich that has spent almost three weeks under George’s bed. Daniel and Ruby are wary in the beginning – they convince George to ask his mum if the sandwich is edible. The little elephant’s mum is in the living room with her friend, who happens to be a professional microbiologist. With her, the three preschoolers will discover a new field of science and a new microworld.
