Every kid who has ever had the dinner-table show-down with their parents over some vegetable they refused to eat will enjoy this tale.  Even when Martha’s parents insist that green beans are good for her, Martha knows they’re really bad.  She’s proven right one day when a gang of personified green beans dressed as hoodlums from the wild west arrive in town, reeking havoc on anyone who ever said, “Eat your green beans.”  When they take Martha’s parents hostage, she’s delighted at first with her new freedom to stay up late and eat whatever she wants.  When she decides she really does miss them, and decides to rescue them, the only way to set them free is to eat all the marauding beans.
