This is a delightful tale about Christmas, wishes and reality. Opus the penguin laments the fact that he cannot fly like the snow ducks. Therefore, he writes a letter to Santa Claus asking for wings that work. Before going to bed on the night before Christmas, he tells a snow duck that he will be flying on Christmas morning. However, as Santa is making his rounds, there is a malfunction of the sleigh connections and the sleigh is disconnected from the pulling reindeer. Santa's sleigh begins to sink in a cold, icy lake and Opus is awakened.
He dives into the lake and swims like he never swam before. Clutching a towrope in his beak, he pulls the sleigh to land. Santa then tells him "I see no penguins here, whose wings only sputter. Tonight it was courage that flew yours beyond others." The next morning a group of snow ducks arrives and carries Opus into the air.
The moral of the story is that when we are wishing for new skills or possessions, we should never lose sight of the value of that we already have. It is done very well and fits well into the general spirit of the Christmas season.
