Zeros to Donuts - When George learns about the meaning and power of zero, he is ready to test out his knowledge. The perfect opportunity arises when he's sent to the donut shop for one dozen donuts. But when he adds a couple of zeros, he's surprised to find out he gets one hundred dozen. Now he has to figure out what to do with all those extra donuts before The Man with the Yellow Hat notices. Curious George, Stain Remover - George spills grape juice on the new rug and needs to figure out a way to clean it up before The Man with the Yellow Hat returns! Too much soap and too much water make matters worse. With the help of the barnyard animals (and some simple engineering), George uses the Renkins' water pump to clean up the mess.
