El Cascarrabias siempre está de mal genio y, además, lleva encima una nube de tristeza. Cuando recibe por accidente un balonazo, su coraje crece y esto lo hace caer a un pozo. Pero lo que pudo ser un desfortunio, es un remanso para el corazón -junto a su hermana, que le hace compañía en la noche-, a pesar de perder poco a poco su melena. Este libro nos demuestra que el mal humor trae problemas, aunque si disfrutamos de nuestro alrededor en calma y con quienes nos aman, la vida es mucho mejor.

The Grump is always in a bad mood and carries a cloud of sadness with him. When he accidentally gets hit by a ball, his anger grows, and he ends up falling into a well. But what could have been a misfortune turns out to be a balm for the heart--especially with his sister by his side during the night--even though he slowly loses his mane. This book shows us that bad moods lead to problems, but if we enjoy the calm and the company of those who love us, life becomes much better.
