"When Groggle and Snarlina get dressed up to go trick-or-treating on Halloween, they hope to fill their pails with yummy loot from all their spooky neighbors. After a quick wardrobe malfunction, which Groggle smartly sets right, they're off to see the werewolf, the witch, the mummy, and the ogre. But no matter whose house they visit, Groggle just can't control his monster appetite!"--Provided by publisher.
