Chief Wizard Hellibore is to give a master class in magic to the girls of Cackle's Academy. This is an ideal opportunity for Mildred to enlist his help to change her newfound frog friend back to his old self. Unfortunately, Mildred has been banished to her room and, as punishment, forbidden to attend the master class. She manages to lure Drusilla to her room and goes to the class in her place. Needless to say, Ethel who has also been banished from the class, exposes Mildred. It looks as though Mildred is in trouble again, especially when Hellibore recognizes her as the the girl who crashed into him last Halloween. Determined to keep her promise she reveals the wizard-frog who she has been hiding under her cloak, and persuades The Chief Wizard to change him back. Lo and behold, the two Wizards are old friends from long ago and there is general rejoicing all around.
