I wish to be a dragon

"I wish to be a dragon," You say.

Suddenly you feel tingly all over your body and then pass out. And when you awaken, you look at your body to see you have indeed changed into a dragon. You look around the area to see you're inside a prison. The room you're in is spherical, and you can hardly fit inside of it. It isn't long for you to realize it's not a prison you're trapped in, it's an egg!
