Having broken the curse to release all the animal souls into the Magic Kingdom, Eric, Alistair and Peter have learnt from Mrs Boniface that one of the Grippids has managed to break through the portal. Rolykins must now take up the task, together with his friends and Baz's help to prevent the Grippid from reaching the fountain of eternal life and multiplying itself. If this happens, it will never be defeated. The Grippid has some other allies, Angoriah and his two serpents and together, Rolykins, his friends and Baz face a dangerous and challenging mission, to pursue and destroy them all and to break the final spell cast on the fountain of eternal life.
