Learning to be a princess is no easy task and fortunately Princess Sofia the First has had some exceptional assistance in this quest from some very famous fellow princesses. Snow White, Cinderella, Aurora, Tiana, Rapunzel, Mulan and Ariel are among those who have passed through Enchancia to share their wisdom with their newest-ish contemporary. And now, as part of an upcoming four-episode event known as ‘The Secret Library,’ Sofia will not only get to meet Merida, but the royal snowman himself from Arendelle, Olaf.

Books scheduled to be published around the event provide some insight into what Sofia and her new friends will encounter.

In ‘The Secret Library,’ when Sofia’s aunt Tilly visits Enchancia, she gives Sofia a special book that guides her to a secret library hidden in the castle. The library is filled with hundreds of unfinished books — and Sofia is the only one who can give each story a happy ending. Sofia selects the story of Minimus’s brother, Mazzimo, who has been captured by the arrogant and greedy Prince Roderick of Borrea. It’s up to Sofia and Minimus to rescue Mazzimo and grant him his one wish: to be free! Merida will make an appearance in this episode, the first of the four episode event, which is being promoted as airing later this year.

Then in spring 2016, we will see the return of Miss Nettle. In ‘The Tale of Miss Nettle,’ Sofia’s amulet summons her to the Secret Library, where she hears the exciting ‘Tale of Miss Nettle.’ It’s up to Sofia to finish the story. Along the way, she meets a very special friend: Olaf the snowman!
