Through their adventures, they have fun, grow up, and learn good manners and proper behavior. Rocky is a messy little monster. Wherever he goes, he turns everything upside down. There are dirty clothes everywhere, scattered toys, and piles of garbage. Chaos, panic, and disorder. But that's not always fun... A funny story that shows children that they can have fun even when tidying up their things!
