While waiting for the man with the yellow hat to buy train tickets, Curious George causes trouble by mixing up numbers on the schedule, but he makes up for it when a little boy's toy rolls toward the tracks.
When the man with the yellow hat tells George that he is planning a surprise, of course George is curious. Before long George finds a hat, noisemakers, decorations, and games. It must be a birthday! But whose birthday is it? That's the surprise!
George is lucky to arrive at the library just in time for story hour. But it's not easy for a little monkey to sit still too long. From selecting books to getting his very own library card, George's day at the library makes reading fun,
George is looking for a way to beat the summer heat. Swimming, running through sprinklers, a glass of lemonade--none is able to help George cool off! What George really wants is a sweet, cold treat from the ice cream truck! But will he ever catch it?
