The boys are besieged by the new crop of Grazlaa who multiply with heat and seem likely to reproduce into millions. Whilst Tom gets rid of school-mate Katie,who has come to the door as a charity collector,Benny works out that the creatures are allergic to high pitched noises and destroys them with his violin playing - spattering the house with their insides. They bring Ursula in to effect a magical clean-up,which also turns the reproduction ornaments into valuable originals.
