Well, the chick grew up into a chicken, but you’re still not sure how the egg got into that cave...

Lil Peepers was fleeing the jaws of a voracious wolf, when she stumbled across the cave. She darted into the opening, hoping that somehow she could lose the terrifying beast in the dark. However she found herself in a much worse situation. Dozens of reptilian creatures stared down at her, dragons! Suddenly the wolf lunged at her, and Lil feared the worse. Instead a huge shield like object descended between them, and the wolf collided into it with a huge crash. A kindly Guardian dragon had saved her. The last time Lil saw the wolf, he was fleeing with his tail on fire. Because of this Guardian's protection, Lil has grown plump and happy in her role as the cave's 'mother hen'.
