Princess Justina Albertina likes getting her own way. Her nanny, when faced with a choice between a headache-inducing royal tantrum or giving in to the princess's demands, always caves. So when the youngster insists on getting the perfect pet, her nanny does her best to oblige, scouring the Earth for unusual animals. None of them is quite right, though: the puffer fish ignores the princess, she cannot ride the two-headed dog, and the monkey scares too easily. Finally, the nanny returns with a fierce gryphon, which the princess declares is perfect. This time, however, Princess Justina Albertina has bitten off more than she can chew.
