Egg ghost refers to dalgyal guishin (Korean: 달걀귀신), a Korean ghost.
It does not have arms, legs, nor a head, not even eyes, nose, or mouth.
Legend says that when a person sees an egg ghost, they will die.
Rumor has it that some of egg ghosts' personalities are not incorruptible as time goes by.
Some scholars interpret that egg ghosts are a kind of mujagui (Korean: 무자귀, hanja: 無子鬼) (literally, a "childless ghost"), which have no descendants or relatives to hold an ancestor memorial service for them.
