Sofia stumbles across a baby bird who has fallen out of its nest and helps it return to its mother.

Despite really being upset, Sofia laughs it off and walks away soaking wet. The swing ride sends Sofia sailing through the air and then into a fountain with a splash. James does so which makes everyone's smiles vanish. Everyone takes an instant shine to Princess Sofia prompting Amber to convince James to give Sofia a ride on the Enchanted Swing Set. Through a song, they tell her that becoming a true princess is something that takes time. Sofia asks them to teach her how to be a true princess by the day of her royal debut ball.

The next day, Sofia, James, and Amber take a flying coach to the Royal Preparatory Academy. On the way back to bed, Sofia bumps into Cedric, who recognizes her new necklace and now wants it for himself. Sofia happily accepts the gift and gives him her word to wear it always and never let it out of her sight. Roland comes out of the shadows and gives Sofia a beautiful necklace that he says is special and tells her she must promise to never take it off. She finds her mother and tells her about her uneasy feelings and that she would rather not have a royal ball because she doesn't know how to dance and doesn't want to let anyone down. Through a song, Sofia reveals her insecurities and her belief that she's not ready to be a princess because she knows being royal has huge responsibilities and she knows she has no experience when it comes to fulfilling them. At the dinner table, Roland tells his new daughter that there will be a royal ball in honor of her royal debut, stating that it's the best way to let everyone know that Princess Sofia has arrived. Sofia is warmly welcomed by everyone at the castle except Amber and Cedric. Upon arriving at the castle, Sofia meets her new father, Baileywick the castle steward, Cedric the royal sorcerer and her new older siblings, Princess Amber and Prince James, the royal twins. They soon marry, making Miranda the new queen of Enchancia and Sofia the kingdom's second princess. It's love at first sight for Roland and Miranda. One day, Miranda and Sofia are called for a shoe fitting by King Roland II of Enchancia. Flora, Fauna and Merryweather appear and introduce Sofia, an eight-year-old girl living in the village with her mother, Miranda who is a shoemaker.
