这本书出版是在1973年，这是一个离奇的寓言：一个城市老鼠访问了他的和平国家的表兄弟们还告诉他们关于这个城市的狂欢节。这个国家的小老鼠们都很激动听到有这么一个属于他们自己的狂欢节。首先，最有趣的是他们戴上有尖牙和獠牙的面具去吓唬他们的小伙伴，但是过了一会儿，他们开始相信他们真的是凶猛的动物。

李欧·李奥尼可爱的老鼠跳跃地穿过大大的双开油画页面上和讲述一个关于“什么是真实的，什么不是”的故事，这是适合学前儿童的故事。精装再版是在2003年，现在它首次用平装上市啦！

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.
