After the recent loss of their mother, the Grimm family leaves their old life to open a pet shop with a paranormal twist. Instead of chubby hamsters and googly-eyed goldfish, you're more likely to find howling werewolf puppies and grouchy griffins at the Little Shop of Monsters. Things seem to be looking up when Gabby and Greta's dad secures three precious dragon eggs to attract customers on opening day. But when thieves get their grubby hands on the eggs, any hope of a new beginning is lost. Determined to fix things for their dad, Gabby and Greta must put their differences aside and track down the thieves before their new start is snatched from them. Time is running out though, and the dragon eggs are about to be sold to the highest bidder...
