Did you know that Unicorns LOVE to eat sweetcorn? In fact, it's how they got the 'corn' in their name. But when one little unicorn gets bored of his corn diet, he decides to change his name to 'Unicake'! He sets off an sugar-eating quest, sampling chocolate, pastries, cakes and biscuits. After Unicake gets a poorly tummy, however, he starts to think that eating sweetcorn isn't so bad after all. He learns that a balanced diet, with lots of fruits, vegetables and sweets, is the perfect way for him to feel his best!
