But when Nancy's friend, Violet, discovers her Make-a-Pet, Hoppity is missing, the Clue Crew is called on to help find the missing bunny. It seems there are a few suspects that could be the culprit--including Violet's best friend, Sonia, who claims Violet stole the idea about Hoppity from her. Could Violet's best friend really be the culprit? Or is the real suspect more of a surprise than they think?
