nuppefuhofu
ぬっぺふほふ (also ぬっぺっぽう)
A nuppefuhofu (also nuppeppou) is "a traditional youkai that is genderless and estimated to be up to 1.5m in height. It is described to have a flabby appearance and its appearance is accompanied by a pungent body odor. It appears as a blob of flesh with a hint of a face in the folds of fat. It is also described as having fingers and toes that are vaguely defined lumps.
"The Nuppeppō is passive and unaggressive. The body odor is said to rival that smell of rotting flesh. Other theories claim that the Nuppeppō is actually decaying flesh. There is a rumor that states that those who eat the flesh of a Nuppeppō shall have eternal youth." [1]
