Monster Menagerie

Kieran is a child monster. He lives in the human world and absolutely loves cooking and baking. But being a kid means you can't own a restaurant in the human world. So he opened a diner in the Land of Monsters. One day he's asked by the head zookeeper, Mr. Green, to help catch a water sprite that had escaped the zoo. He reluctantly agrees and goes on an adventure with his best friend, Lysander, the child of the Grim Reaper, to get the water sprite and bring it back before it's too late. 

Life was slowly getting back to normal for Kieran after he helped Waverly a few months ago. Perry was getting the Menagerie running better with the help of his new assistant, Ridley. But of course, sometimes things just happen that put a screw in your plans. Lysander shows up and brings Kieran to see Perry, and they find out that there is a new monster that escaped the zoo. Now they have to come up with a new plan on how to catch it and bring it back before it's too late.
