Jeff, Mara, Brian, and Kelly are Goofballs and proud of it. Goofball private eyes. Together, they solve mysteries. How do they discover the truth? They use funny disguises (dressing up in aluminum foil), nutty inventions (dropped notes the bad guys must stop to read), and their secret weapon: Sparky the Goofdog! When super-rich kid Randall Crandall asks the Goofballs to help him protect his world-famous collection from a notorious thief, they can’t wait to get started. Randall’s hosting a superhero party, and the detectives will have to blend in to sniff out the criminal. Crazy costumes and off-the-wall schemes mean this is going to be the Goofballs" goofiest mystery yet.
