Melly's learned a new trick, and she can't wait to show the cats. But when they all head outside to play, Melly accidentally loses her ball down the magical hole in their backyard. So she decides this is the perfect excuse to visit her friends in the fantastical world on the other side. And this time around, the cats want to come too. (After all, they need to find someone to open their cans of food!)
But instead of a warm welcome, the group discovers the whole kingdom has fallen into a mysterious deep sleep. And it is all thanks to Wilma, the wizard who long ago took Narra's powers. She's back to finish what she started by stealing the magic of other mythical creatures so she can become the greatest wizard ever. Now Melly and the cats are all that stand in her way. But how will these four ordinary pets stop an extraordinary villain? Well, they may just have a few tricks up their sleeves!
