Jeff Bunter is the #1, original Goofball. Jeff was born to solve mysteries. He is in charge of keeping track of clues in his ever-present cluebook. He says that a private eye has to notice everything—because you never know what might be a clue!
Brian Rooney is Jeff’s best friend. He’s an inventor who loves to build crazy things that don’t always work but that look really cool and help the Goofballs solve mysteries.
Mara Lubin is as tall as a fashion model, as skinny as a rake handle, and wears giant green glasses. She’s also a master of amazing disguises.
Kelly Smitts is as smart as a computer, but she doesn’t look like one. Unless a computer is really short, really suspicious, and has curly yellow hair.
Sparky is the official Goofdog. He’s Jeff’s scruffy Pembroke Welsh corgi and he herds clues to help the Goofballs in every case. Goof! Goof!
