While the Lights are Out

In Pawville, a wonderful museum for cats is made! Going by the name of Felis Cutus Museum, it has been opened to all cats. Not long after its opening, it got closed down due to health concerns. Ever since, someone or something has been stealing the museum's treasures. Detective Barney must figure out how and why before it's too late. All he knows is that this is happening while the lights are out.
