The show follows the adventures of two cousin mice, Alexander from the city and Emily from the country, who go on adventures around the world in the late 19th and early 20th century, usually to help their cousins, solve a mystery, or stop the evil rat, No-Tail No-Goodnik. The two main characters originally appeared in the 1993 television special
The Country Mouse and the City Mouse: A Christmas Tale, which was produced by Michael Sporn Animation for HBO. Loosely based on the classic Aesop fable, the television special was also adapted into a book in 1994, titled
The Country Mouse and the City Mouse: Christmas Is Where the Heart Is. But the characters were modified for the Cinar series. ==Main characters==
