Dragon has a bedtime ritual of saying goodnight to his feet, his fingers, his tail and finally, goodnight to the moon. One night he wishes goodnight to the moon and suddenly notices it now has a small crescent shape missing! Astonished, he thinks the moon is starting to shrink! He's so upset he calls Ostrich to help him find the missing piece of the moon. After spending half the night fruitlessly searching, Dragon decides to wait until morning - so he can search for the missing piece in daylight. He still can't find the missing piece! Then Mailmouse comes by and explains why the moon seems different and reassures Dragon there's nothing to worry about because the moon will always be in the sky.
