Take Me to Your Weeder (How to Be an Earthling Series #3)

Everybody loves the class vegetable garden-except Jack. He doesn't want to pick beans. He doesn't even want to take care of the class hamster over the weekend, and Jo Jo is way more fun than a green bean! That's when Jack has a great idea. He'll get Spork, the new alien in school, to watch Jo Jo. What could possibly go wrong?
