1x21 - Curious George

After a rainy country day, George finds a flock of ducks that have taken refuge in a puddle and spends the day playing with them. The next day George sees that the puddle has shrunk and the ducks are flying off one by one in search of more water. He is determined to do anything to get them to stay around. Then he sees his pool, filled with water and empties it out to get it to the top of the hill where the ducks are. But afterward, he must find a way to re-fill it.
