During Ventuss' visit, he assists her mouse friend, Jaq, in making a dress for her while Cinderella finishes her chores. Despite his appearance, Cinderella believes him to be a mouse due to his unexpected miniature size.
Cinderella's stepsisters angrily tear apart her dress, and Cinderella runs to the garden in tears just as Terra arrives, who encourages her to continue to believe in her dreams for a better future. Eventually, her Fairy Godmother helps her make a beautiful princess gown and a carriage to take her to the ball, with Terra as her bodyguard. While at the ball, she meets the Prince, and they fall instantly in love with each other. While dancing, she and the prince are suddenly interrupted by a gigantic Unversed until Terra comes to their rescue.

As she runs through the Grand Hall, she loses a slipper.
