Gus gets trapped in a tea cup and Lady Tremaine offers some tea to the Duke, with Gus inside. While trying to steal the key, Jaq is stuck in Lady Tremaine's pocket.

Later, Jaq and Gus are responsible for stealing the key to Cinderella's room from the wicked stepmother, Lady Tremaine, and freeing Cinderella to try on the glass slipper, which of course fits. Jaq and Gus are two of four mice that the Fairy Godmother transforms into stallions so that Cinderella can attend the ball, but at the stroke of midnight, they are transformed back into mice. Cinderella names him 'Octavius,' and calls him 'Gus' for short.

Gus appears in the first scene of the film, trapped shivering in a cage where Jaq finds him and brings Cinderella to rescue him. Jaq is thin, with scruffy hair, and speaks a fast kind of pidgin English. Jaq seems to be one of the leaders of the mice, planning strategies to avoid the cat, sneak food, and help Cinderella with her ball gown. Other than his friends and family, his number one priority is filling his belly.Д¬inderella rescues the mice from traps and the cat Lucifer and dresses and feeds them. He is Jaq's best friend and is rather dim-witted compared to his buddy. Octavius (also known as Gus or Gus-Gus) is a portly brown mouse wearing a yellow shirt, green hat, and brown shoes. He acts as the leader of Cinderella's mouse friends and proves to be a good one at that. Jaq (also known as Jackson Checkers) is a slender brown mouse wearing an orange jacket, red turtleneck, red hat, and brown slippers.
