A comedy adventure from Magic Light Pictures. Princess Pearl, Sir Gadabout and Zog the dragon make a most unlikely flying doctor team, yet they are committed to treating all kinds of creatures, real and mythical, including a mermaid, unicorn and lion. When the King captures Pearl, she has to choose between her freedom and curing her increasingly sick uncle. With Zog and Gadabout's help, she finds a way. Based on the picture book written by Julia Donaldson and illustrated by Axel Scheffler.
