If you have read the book, Hold On To Your Pants, you know what a Kallaboo is. If you haven't, it is a make-believe animal that you might get if you were to cross a koala bear and a Wallaroo (which is a small kangaroo). Hold On To Your Pants is about young Kallaboo parents with their child. This book is about the parents after they got older, and their child grew up and moved out. They are called Maw and Paw Kallaboo. They are enjoying a quiet life, dealing with whatever comes their way. Paw Kallaboo's biggest problem in life is that his pants keep falling down.
