Bob nervously pops a sweet into his mouth as he stands outside the door of the Pets 'n' Friends Detective Agency. He has an appointment with Skeezle, the agency's top private investigator. Bob needs to talk to Skeezle about what he saw a couple of days ago while out for a walk. He passed a notice on a neighborhood wall stating that "Kilroy was here". What Bob needs to know is who is "Kilroy"? Not knowing Kilroy's identity is ruining his appetite. You see, when Bob gets nervous or upset, he eats chocolate sweets - lots of them. Bob is hoping that Skeezle can solve this mystery quickly.
