Einstein the class hamster

Einstein the class hamster is from a long line of class hamsters. He knows lots of cool facts about science, art, and history--maybe even more than their sleepy teacher, Ms. Moreno. The class has a chance to compete in a trivia game show contest. But how can they get ready for the contest if Ms. Moreno keeps taking naps instead of teaching? More important, how can Einstein help the class prepare for the contest when the only kid who can hear him is Ned?.
