Tenome

Also, Inui Yūhei depicted a yōkai called the "tenome" in an old illustrated manuscript currently owned by the Shisui Library (date of authorship unknown) where it was introduced with the words "are taru kusamura nado ni amatsuchi no seisei ni te shiyazu to ifu" (あれたる草村抔に天地のせいせいにて生ずと云, "these are said to be born from the grasses and grow from the land and sky.

"[4] In the collection of kaidan, the Edo-period Shokoku Hyaku Monogatari (1677), there is the setsuwa titled "Bakemono ni Hone wo Nukareshi Hito no Koto" (ばけ物に骨をぬかれし人の事, "How a Person Had Their Bones Removed by a Monster") illustrated with a yōkai that had an eye on each hand, and this monster is thought to have been designed based on Sekien's "tenome".

The man fled into a nearby temple and after he made the monk there let him conceal himself in a nagamochi (a kind of chest), the monster chased after him, whereupon there was a sound like that of a dog sucking a bone, and after that it finally disappeared.

[7] The yōkai researcher Katsumi Tada gives the interpretation that these drawings of the yōkai "tenome" and others are a word play on the phrase "bake no kawa ga hageru" (an expression meaning "to give away/reveal one's true character", literally meaning "to peel off one's layer of disguise").

He explains that the background of the "tenome" in the Gazu Hyakki Yagyō has a moon and a field of susuki, so the whole drawing is telling a joke with the moon indicating the bōzu (meaning "bonze" or "baldie") card in hanafuda (bōzu is an alternate name for the August suit) and the susuki being a reference to the kotowaza phrase "yūrei no shōtai mitari kare-obana" ("look at the ghost's true identity, it's a withered obana"), an expression about being so paranoid that anything, even withered obana (an alternate name for susuki), might seem like ghosts.
