Cinderella gives cute names to all of the mice she rescues. She named the fat mouse 'Octavius' but for short calls him 'Gus'.
Jaq and Gus help 'Cinderelly' get ready for the ball, by getting materials for her dress, and helping her escape from her room after the wicked stepmother locks her in!
In a far away, long ago kingdom, Cinderella is living happily with her mother and father until her mother dies. Cinderella's father remarries a cold, cruel woman who has two daughters, Drizella and Anastasia. When the father dies, Cinderella's wicked stepmother turns her into a virtual servant in her own house.
Meanwhile, across town in the castle, the King determines that his son the Prince should find a suitable bride and provide him with a required number of grandchildren. So the King invites every eligible maiden in the kingdom to a fancy dress ball, where his son will be able to choose his bride.
Cinderella has no suitable party dress for a ball, but her friends the mice, led by Jaques and Gus, and the birds lend a hand in making her one, a dress the evil stepsisters immediately tear apart on the evening of the ball. At this point, enter the Fairy Godmother, the pumpkin carriage, the royal ball, the stroke of midnight, the glass slipper, and the rest, as they say, is fairy tale.
