After his last run-in with Vince the Funnel and the mystery of the missing chicks, J.J. the search-and-rescue dog is ready for some much-needed R & R. But just when he thinks he has everything under control, there's a new problem to worry about: Diamond Lil, a new show dog who's taken up residence next door. Suddenly Moosh and her chicks are spending an awful lot of time with their fancy friend, talking about weird things like feathers and good posture. And Lil's not the only new kid cramping J.J.'s style. There's a possum loose, and it's up to J.J. to keep everyone safe. But the questions are piling up. Is Lil all that she seems? And how does the possum keep finding her way to the chicken coop?
