"Gaston is just like the rest of the unicorns. Except for one thing: the color of his mane always reflects his emotions. When Gaston is very happy, his mane shines in the colors of the rainbow. But sometimes the little unicorn is sad, or jealous, angry, or perhaps afraid. He has just been offended , and he is not well at all. Grayness reigns in his heart. What should he do to get rid of his sulking?
Illustrated with charming pictures, the stories of the book series tell one of Gaston's adventures and also describe breathing exercises that help you understand emotions, fully experience joy or overcome bad feelings. We recommend it to kindergarteners, their parents and kindergarten teachers alike."
