Professor Puffendorf's Secret Potions - Robin Tzannes

Professor Puffendorf is a world-class inventor: where would any of us be without her Unburnable Toast or her Smell-o-Telephone? She shares her laboratory with her much-loved guinea pig, Chip, and Enzo, her rather lazy assistant. One day, when the professor goes out to address a conference, Enzo opens her 'top secret' cabinet. Inside he discovers an array of potions promising to deliver anything from curly, luxuriant hair to a beautiful singing voice. Enzo realizes the secret formulas for these potions could make him unbelievably rich but first he decides to test them on poor Chip. However his devious plan does not quite go as he imagined and it is the villainous Enzo who ends up as the guinea pig - quite literally - in this entertaining cautionary tale of role reversal.
