Originally published in 1973, this is the offbeat fable of a city mouse who visits his peaceful country cousins and tells them about Mardi Gras in the city. The country mice are inspired to have their own Mardi Gras. And at first, it is fun wearing their masks with sharp teeth and tusks and scaring each other, but after a while, they begin believing that they really are ferocious animals. Leo Lionni's winsome mice cavort across big double-page spreads of oil paintings and tell a story about what is real and what is not that is just right for preschoolers. Reissued in hardcover in 2003, it now makes its debut in Dragonfly paperback.

城市老鼠告訴住在鄉下的老鼠表親們城裡慶祝狂歡節的盛況。原本過著寧靜生活的鄉下的老鼠聽了之後也想辦一個狂歡節。起初他們戴上尖牙利齒的面具互相嚇對方，久而久之，戴著面具的老鼠忘形的以為自己真的就是猛獸。本書作者為國際知名的繪本大師李歐．李奧尼 (Leo Lionni)，以跨頁油畫呈現小老鼠們快快樂樂唱歌跳舞的樣子，也藉此引導學齡前兒童分辨真實與虛假。本書最早出版於1973年，2003年再度推出精裝版，平裝版則於今年首度上市。
