From far and wide the garden creatures come to Dr Earwig's surgery under the shed. It is a hospital like no other. The Doctor never knows what kind of creepy-crawly his next patient will be. All are treated with kindly care, wise words and marvellous medicines. Dr Earwig and his assistant, Nurse Ant, have home-made remedies for all occasions and the Doctor's emergency bag is always packed. They are ready at a moment's notice to help any garden creatures who are sick or injured - moths and millipedes, stag beetles and spiders, worms and even wasps are welcome.
