The little penguin feels lonely on his beach. Everyone around him is black and white and wants nothing to do with him because he is blue. So he sets off on a journey and actually finds a friend who has the same color as he does. Friendship is indeed blue - or is it? The little penguin gradually learns that there are many different beings in the vast ocean. Friendship is colorful, and diversity enriches togetherness. In our current situation, where exclusion is common, this picture book makes this important thought visible. The final image includes a cut-out sheet for self-designing and a song that rounds off the story.
