No one knows how Billy got the nickname “The Quack”, and no one is really brave enough to ask him. Because Billy is as tough as nails, which if you think about it are harder than ducks. Kinda.
Billy is the most skilled wassie detective in the history of the universe. He has a shrewd mind (for a wassie) and he never gives up on a task he has set his mind to (largely as he has never set his mind to a task). Some say his hat keeps his brain at the ideal temperature for solving crime. Others say his fuzzy body makes him naturally adaptable and able to think around corners. Either way, if you have a mystery, you need Billy “The Quack” Vantooso.
