While visiting the Kingdom of Wei-Ling, James and Prince Jin set off to search for the legendary treasure of the Jade Jaguar but soon find themselves trapped in the jaguar's den. It's up to Sofia, Amber, Princess Jun, and a very special Disney Princess to rescue their families! This beautifully illustrated picture book is based on a special episode featuring Mulan airing on Disney Junior in Summer 2014, and comes with a bonus downloadable song, "Stronger Than You Know," from the episode!
