Jessica pretends to be the real Santa so that Evan will believe that Santa is Chinese rather than a white man.

The boys realize that their "dish-drying rack" is actually a dishwasher.

When the other mice warn of a cat, Fievel doesn't believe them. His father once told him that cats don't exist in America, and he shares that belief. He changes his mind and runs for his life when a black cat attacks him in an attempt to eat him.

Mice from all over group up and create a plan to drive away the cats, who threaten their livelihood. They created the Giant Mouse of Minsk, which they call their "Secret Weapon," and used it to scare away all of the cats in the city.

Jessica is worried that her children will lose touch with their Chinese culture, so she redecorates and sends them to Chinese school.
