One day, a little mummy decides he wants to be more independent, so he tells his mom he's going to run away from home. "If you run away," says his mother, "I will get you! For you are my rotten little mummy!" And the good-natured chase is on! The little mummy disguises himself as a series of larger-than-life monsters: a serpent, a gargoyle, a huge bat. With each new transformation, Mother Mummy transforms herself, too, so she can be with her son. It's only when the little mummy disguises himself as a kid getting tucked into bed that Mother Mummy is forced to let loose her most spine-tingling shriek and scare the would-be parents away. It's all in good fun, and the little mummy is so delighted to see his mom come to his rescue once again that he pledges to be her "rotten little mummy" forever. This lighthearted parody of the famous picture-book classic The Runaway Bunny is full of wacky monsters and spooky situations, but it is never scary. What shines through is the love shared between a mother and her child. A sequel to Goodnight Goon, the first "petrifying parody" in the series, this funny tribute is destined to become a new bedtime classic.
