Groggle met Snarlina at her house one spooky night. A swarm of bats was fluttering. The moon was shining bright. 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! Snaaarf! Slobber! Cruncha-muncha! Crispy bones, lizard tails, spider pops, slugs and snails . . . Groggle gobbles them up before they even land in his pail! At the end of the night, Snarlina sifts through her treats while Groggle watches on, having eagerly eaten all his treats. Can friendship save this spooky holiday? Find out in this monster of a tale.
