Chansey is a pink, spherical creature that has short arms and feet of the same color. It has small eyes and three tufts of hair on each side of its head that are also pink. On its belly is a pouch that contains a single white egg which is said to be very nutritious. This egg lays several new ones every day. Chansey is female-only species without any male counterpart.
Chansey is known for its kind nature as it shares its eggs with injured people and Pokemon but never shares it with those who have evil hearts. If raised with love and care, its eggs become more delicious. Due to its egg being over-harvested, Chansey is extremely rare in the wild and brings good luck and happiness to those who catch it. It has become quicker on its feet than before due to people seeking its egg. It is commonly found in urban settings.
Chansey can use the Lucky Punch item and in Pokemon Legends Arceus, if injured, any nearby Chansey will come to check them out before fleeing when fully healed. However, it does not actually heal the player.
Chansey evolves from Happiny into Blissey.
