To carry out her mission, she has to become a normal girl of Harmony Town, living and working in the Heartrose Bakery, and has to lead a double life. While she spends most of her time with her new friends or the Royal Teeniepings, she has to transform into a princess as soon as she sees a freed Teenieping around, as they like to wreak havoc in all of Harmony Town and try everything to not be caught!
