This year, Dodo wishes for "almost nothing" for her birthday, just a fish. Fortunately, this dream comes true, along with an aquarium and beautiful water plants. But a fish is more than just a fish. A fish can talk, changes its color at will, is never tired, and doesn't need sleep. No matter how often the parents come into the room to send Dodo to bed, the girl shows the fish her world and her games. In return, the fish shows her how wonderful life is underwater. In this enchanting picture book, even unusual children's wishes come true - with imagination.
