In Secret Agent Dingledorf's sixth top-secret case, everyone's pets are going crazy! Cats think they can sing opera. Dogs think they're country-western stars. Even Priscilla's turtles think they can yodel! Only Secret Agent Dingledorf and his trusty dog, Splat-created by the outrageously funny Bill Myers-can solve the case and save the day. Black-and-white illustrations bring the mystery to life as everyone learns a little lesson about the importance of treating pets and animals with kindness.
