This egg was only available in Egg Cave's Cash Shop Park for February 2012.
Corphex eggs are very bright; they absorb all kinds of light except rare forms of blue, purple, and magenta (which is what they reflect).
First-stage Corphexes are a common gift between young couples. Corphexes are regarded as a symbol of young and pure love. More developed Corphexes are symbols of eternal love or "love that is enduring." If a Corphex dies prematurely, it is said to be a sign of bad luck for one's love life.
