Today is the big day in Toby's class. The team that presents the best project about an original object will win tickets to the Circus of the Stars. So far, the class has come up with presentations about ukuleles, a collection of stamps, a turban and a ferret. Toby is sure that he and Marianne have a great chance of winning. Their project on eclipses is out of this world! Or at least that's what Toby thinks before seeing the little green box where Arnold guards his mysterious creature!
