Audrey Plum is borrowing her first pet from the Pet Library. She wants the perfect pet. And she thinks she's found one. Robert. She just has to keep him-and his big front teeth-away from the turkey rug at home. When Robert turns out to be a bit of a disappointment, Audrey wonders if she might not have a "defective" bunny on her hands. Meanwhile, everyone's favourite frog, Prince William, has gone missing. Audrey and her friends form a search party to help find him. Is Prince William really lost or has he fallen victim to yet another one of the high school's science experiments. Tempers rise and things get a little scary in this Pet Pal adventure...thank goodness Ms. Swan is around to lighten the mood with her endless frog jokes.
