Curious George Season 2 Episode 22

Creatures of the Night

When Bill tells George it was a possum that ate the bird food from the bird feeder, George stays up to see what a possum looks like. But then he notices that it has lost its family, so he looks and finds it. Along the way he meets more nocturnal animals and makes almost everyone in the country think he is "The Lake Creature of Lake Wannasink Lake".
