In Moonstruck, Uno, Duo and Trio, are not feeling very happy. One night, the animals get woken up just before Midnight and the rats tell the animals that they are going to eat the moon. The animals try to stop the rats, but they just check up on the moon every single night at 12am for a week and do a drawing. By the end of the first week, the moon is only half the size it was at the start.

After two weeks, the moon disappears. In the end, Ginger the Cat tells the animals that the moon only SEEMS to get bigger and smaller. Then, the animals give Uno, Duo and Trio some food and then, the moon gradually grows back, and after 2 weeks, the moon is back at full size again. The animals then have a midnight feast down by Brenda's pond, and all is well.
