Well, everyone saw this coming…With an appetite fit for the King of the Fen Wolves, it was only a matter of time before Routa grew too big for the mansion. This dog needs diet and exercise! …Okay, that's too much effort. Thankfully, there's more than one way to achieve a smaller form, and he knows just who to turn to for a lesson in shape-shifting! But as the full moon rises, Routa soon learns that a battle with weight loss isn't the only challenge headed his way -- Carmilla, haughty vampiress and a general of the Demon Lord's army, takes the stage! And she's got her sights set on Lady Mary!
