Gruntly is a literal and metaphorical hog who serves as his own comeuppance in this gentle, if spirited, admonition.
"If there was a something, he wanted it all. All for himself." And not just all the toys and stuff; he wants the wool off Woolworth's back, the feathers out of Cluck's tail (" 'Cluck,' Cluck said...She was a chicken of few words"). Comes the day of the treasure hunt, and Gruntly has visions of gold and silver dancing in his big, selfish head. He also has too much greedy energy running through his system to pay attention to the clues and so is thwarted in his quest for world domination of treasure. Cluck of Few Words provides the necessary minimum for Gruntly to get his rightful share. Gruntly is stunned by "his companions' kindness and generosity," and becomes a changed pig, a better pig. Team Lester/Munsinger are a success because they are simple, direct and elementally charming. Lester is all for the droll use of language—"then Cluck got down on her knees (or whatever chickens get down on")—while Munsinger is majestic in the use of body language, and her piggy perp is always more a clown than a creep.
Given a name like Gruntly, there's little to expect but greed, but this pig flies to higher ground. (Picture book. 4-8)
