It's time for the Summer Fete Baking Contest and the Mr Men and Little Miss are all getting ready to compete. Little Miss Neat has measured all her ingredients very carefully, whilst Mr Impossible is baking his pineapple upside down cake ... upside down! Who will the judges choose as the winner? And will anyone remind Mr Forgetful to turn his oven on? Mr Men and Little Miss Celebrations introduce children to all the exciting occasions that people celebrate including sports day, a visit from the tooth fairy, Halloween and Chinese New Year.
