Dragons don't really exist, but Cat knows some lizard friends who are oh-so like dragons! They can show Nick and Sally how to pretend to be dragons. The first one they meet is Ignacio the green iguana who shows them his spikes and dewlap. Then it's off to meet Draco the flying lizard who has wings! Kimora the komodo dragon is the last stop, she shows the kids her long wiggly tongue. Now, with some help from things around the house, Nick and Sally know just what they need to be dragons!
