MEET THE MERCUSONS by Debby Feo

Yes, meet the Mercusons. They live on the planet Mercury. In many ways, they're just like you, if you wear space suits, and have a tail, and can dig holes with your tail. The Mercusons take vacations, go to school, and celebrate birthdays. Of course, because Mercury's year lasts only 88 days, the Mercusons celebrate birthdays very often.
 
Come inside and meet Eelo and Chite Jelo and Rela and Pelo. See what kind of trouble they can find to get into. Maybe you can help get them out of it.
