The Blue Monster is a friend of Rosa. You all know him from the previous books in the series, but now it's time to learn his story. Unlike Rosa, he is born in a colorful place where no one looks like the other except for one characteristic: they are all the BEST. One monster jumps high, another is strong and throws stones far away, the third has the strongest voice. But what happens when the Blue Monster realizes that he doesn't know what he is the BEST at? What is the skill in which he excels and ultimately what can he do with those huge hands?

A tender story that speaks of the virtue of empathy, respect, and the concept of coexistence, reminding us that what matters in a society is the moral excellence of its members.
