Oscar the Caterpillar has been wrapped up in his chrysalis all winter long, and today's the day he emerges into the world as a beautiful orange-tip butterfly. It's a big transformation from a wriggly caterpillar to having wings. Luckily for Oscar, there are some friends around to give him a helping hand.
