Felix wakes up feeling ill because he has eaten too many 'chocolate blimpies' the night before. His mummy tries everything to make him feel better, but he is still peaky. Doctor Duck says to bring him to the surgery, but Felix is frightened and doesn't want to go. Mainly he is worried that the doctor will make mummy leave the room, but she is with him all through the examination and while the doctor gives Felix 'two spoonfuls of Happy Tummy'. Then he sleeps a long time and feels fine again. I think Felix and his mum are guinea pigs, but whatever they are, Felix is cuddly and lovable, and the relationship between mummy and Felix is a delight.
