Mo is a monster who just got a mustache. A big, black, beautiful mustache. Everybody likes Mo's mustache. Now Knot, Dot, Nib, Tutu, Bob, Bill and Ben all have mustaches too. In fact, soon EVERYBODY has a mustache! Why is everyone copying Mo? And how will he (and his mustache) ever stand out? A wonderfully silly book about style and individuality, sure to grow on readers who don't have facial hair -- and even those who do!
