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

Cherty is a pleasant tempered chicken who is very fond of Summer Forever, a frozen summer hatchling.  Cherty thought Summer's egg was hers and spent hours sitting on it trying to help it hatch.  Now that Summer is out of the egg, Cherty can always be found nearby, clucking with contentment over her fine "chick".
