S7E6 Lil' Crime Stoppers

The boys are engaged in a game of "junior detectives," tasked with locating a stolen doll. After a thrilling rescue, they find themselves at the Park County Police Headquarters. There, the Chief elevates their status to "real" junior detectives and hands them their inaugural assignment: shutting down a meth lab. As they dive into this new role, the boys quickly realize that being actual detectives isn’t quite as enjoyable as they had imagined.
