Little Miss Neat非常愛干凈，她住的地方總是一塵不染，而秋天是她最討厭的季節，為什么呢?因為秋天葉子會開始掉落，而Little Miss Neat原本整齊干凈的花園就會有礙眼的落葉。每掉一片葉子，Little Miss Neat就會跑到花園去把葉子撿起來，都進垃圾桶里，一整天下來，Little Miss Neat來來回回不下數百次吧，把Little Miss Neat給累死了！某天，Mr. Happy經過，建議Little Miss Neat可以等樹葉全部掉光在一次清理會比較快，但是Little Miss Neat實在是受不了臟亂，她在樹下等阿等，等阿等，等到最后一片葉子掉落，但當大多數的葉子都掉完了，樹上記然還剩一片葉子，Little Miss Neat當下愣住了，不知該如何是好！好險有Mr. Happy的幫忙，他把最后一片葉子直接給摘了，Little Miss Neat太感激Mr. Happy了！到了最后，Mr. Happy還給了Little Miss Neat一個小建議，讓她到了明年的秋天時可以不用這么勞累！

Mr. Men and Little Miss Get ready for the second invasion of Little Miss and Little Mr. Men! That's right - those zany, pint-sized characters are back. Easy enough for young readers and witty enough for adults! Little Miss Neat keeps her home as tidy as can be -- until Mr. Muddle comes to visit!
