The Only Blue Crow

There's a blue crow who doesn't know anyone like him. At times he feels terribly lonely.
“Luckily in my home valley there are blue flowers, blue butterflies and a blue sky,” he ponders. The blue crow feels even sadder when the new neighbors, black crows, mock him.
On the advice of a wise owl, the bird embarks on a journey across the sea. There are plenty of things to see. Will there also be other blue birds, and perhaps even another blue crow?
