Have you ever seen a desperate duck? No? Well, you are not alone. Bunny and Jack have never seen one either. And as crack investigators and top-notch private detectives . . . well, let’s just say Bunny and Jack have seen it all. Until Mabel. But why is Mabel desperate? As our private eyes soon discover, Mabel is missing her sugar cubes. This may be bad news for Mabel, but it’s good news for Bunny and especially Jack. Jack loves a mystery involving sugar because the clues inevitably lead to cookies, pies, cakes, candy, ice cream . . . and in this case to a young ferret and a homework assignment. Case closed! Desperation dispatched!
