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

Stories have been passed from generation to generation about entities called 'Space Chickens', chicken-like creatures who believe that their kind was sent to Earth from a distant planet, known by some as Clucktopia, in an attempt of universal domination. Yolkhan Spacebastian Bock was named for both the composer that used to lull her to sleep when she was just a little hatchling, and her stories of supposedly being a Space Chicken. A quote from Yolkhan herself, directly translated from chickenese:

"I was brought up by hic a couple er hams... er, hamhicsters... Them fuzzy things. They teached me the ways of... hic of uh.... the space... space chi... chicken... socks..." Yolkhan then proceeded to pass out on a rock in the middle of the cave.
