George loves making friends. And this new one is unique! He stays flat on the ground and is shaped just like George. Whenever George waves, his friend waves back and follows George wherever he goes. George's new playmate sure is friendly ... but quiet! Allie explains that this friend is actually George's shadow, and Allie has one too. Even more amazing, The Man with the Yellow Hat shows them how to make shadow puppet animals, like a rabbit, dog, and a bird! When Allie needs visual aids to tell her flying cow and duck story at Storytime Showcase - and she can't fit Leslie the cow through the library door! - George tries to use what he's learned about shadows and shadow puppets to help Allie tell her fantastic tale! / George loves celebrating Founders Day in the Country. There's music, dancing, costumes and a picnic! For a special exhibit this year, Mr. Renkins brings a truck full of old-fashioned gadgets, like wooden sock stretchers, an old-timey apple picker, and a squirrel-shaped nutcracker. George and Allie have never seen anything like these doohickies before! They learn that Mr. Renkins' Great-Great-Grandfather Zebediah was a peddler who drove a horse-drawn wagon - like a store on wheels - and sold inventions like these to make folks' lives easier. So George and Allie get a great idea. They can make their own gadgets! But what? And how? Using everyday objcts, George and Allie have a blast creating their own thingamajigs. But - are their inventions helpful? When George and Allie arrive at the Founders Day picnic, will anyone want their ponytail holders, tummy scratchers, and reacher grabbers??
