He can swim really fast, is always in a good mood, and laughs a lot. Playing ball and sliding on ice with him is a huge amount of fun. The penguins are very happy to have come across Kautschuk and to be able to meet him again and again. However, one day something happens that changes everything. A friendship that seemed carefree suddenly threatens to break apart. Because Kautschuk is different, he has no beak - not at all! And he doesn't even speak Penguin. In quiet, restrained images full of atmosphere and open spaces, accompanied by few words, Isabel Pin tells a moving story that is ordinary but must not remain so. A story about boundaries, exclusion, hasty judgments, and the seemingly foreign. Meanwhile, the penguins have something that many people unfortunately often lack: they can learn from their mistakes.
