Zog, super keen student turned air-ambulance, still lands with a crash-bang-thump. With his Flying Doctor crew, Princess Pearl and Sir Gadabout, they tend to a sunburnt mermaid, a unicorn with one too many horns and a lion with the flu. But Pearl’s uncle, the King, has other ideas about whether princesses should be doctors, and she’s soon locked back up in the castle in a crown and a silly frilly dress! With a bit of help from her friends, will Pearl prove princesses can be doctors too?
