"Mr. Messy" - Roger Hargreaves

I love these books because the artwork is sooo cute! And I'm a sucker for a series. They have short lessons (happiness is infectious, not everyone likes to be tickled, helping others, etc.).

Mr. Messy is REALLY messy. House, yard, self, habits, all messy. He goes walking one morning and meets 2 gentlemen: Mr. Neat and Mr. Tidy. You can guess what follows.
