Sofia's birthday is coming, and Prince Hugo has made a special gift for her: a beautifully handmade music box that plays a song his grandmother used to sing. But Amber doesn't think Sofia will like it and insists Hugo give Sofia a "better" gift. After many failed ideas, Hugo insists on giving Sofia the music box. But during the surprise birthday party, Sofia really isn't happy because it's very extravagant, and she feels like nobody cares about her. Luckily, Sofia's amulet summons Princess Tiana, who teaches the kids (especially Hugo) that a true gift needs to come from one's own heart.
