Puppyhood's End

Another Wally Pazooza detective case. Near Killington, Vermont a devil is seen hiding out in the Colonel's backyard. Men in black capture a devil thirty miles away, and they are keeping him in a holding cell. Puppy's begin disappearing all over the United States. Wally and his crew move into a mansion near the Colonel's. Do the disappearing puppies have anything to do with the devils? Are the devils real? Or are they humans dressed up as devils? Will the devils invade the Earth and kill us all? Or will Wally solve the case, save the puppies, and stop the invasion?
