Whirr! Whomp! Grind! Chomp! How long can three busy trucks keep it up before...MELTDOWN? Three toy trucks have big plans for their day at the playground: digging and lifting, building and shifting. But then they start to get tired...and hot...and hungry....They're GRUMPY! When they throw a total truck tantrum, will anyone be able to calm them down?

Kids (and parents) may just recognize themselves in this entertaining take on getting grouchy--and getting over it. The lighthearted, rhythmic text will have young readers chanting along, and the bright and buoyant illustrations of the trucks' looming meltdown will keep them giggling!
