Chansey are cheerful, kind Pokemon who love helping others. They are capable of healing wounds and even granting happiness by sharing their eggs with those in need. They are able to lay many eggs every day, even on command. It is thought that they are able to store semen in their bodies indefinitely using their incredible powers to heal, and therefore are always able to produce eggs. This coincides with Chansey being willing and eager to mate with just about anything. Despite being a medium sized Pokemon, their genitals are large, elastic and stretchy, and their massive health enables them to take the roughest poundings with joy. Semen from anything outside their egg group will result in an unfertilized egg of energy used for their healing purposes; a Happiny egg will never be sacrificed in this way.
