"The Tale of Johnny Town-Mouse" by Beatrix Potter is a children's book written and illustrated in 1918. Based on Aesop's fable "The Town Mouse and the Country Mouse," the story follows Timmy Willie, a country mouse who accidentally travels to the city, and Johnny Town-Mouse, his urban counterpart. When each mouse visits the other's home, they discover the unfamiliar lifestyle—complete with frightening cats, cows, and lawnmowers—challenges their comfort. Their experiences lead both mice to a clear conclusion about where they truly belong. (This is an automatically generated summary.)

After visiting each other’s homes, Johnny Town-Mouse and Timmy Willy who lives in the country, decide that they prefer their own place.
