画図百鬼夜行
The Gazu (illustrated reference) above depicts a woman with an elongated lower body next to what appears to be a brothel. However, the "Gazu Hyakki Yagyō" has no explanatory text, so it is unclear what kind of yōkai this depiction was intended to be. Some believe that this yōkai was an original invention designed to parody the Yoshiwara Yūkaku of the Edo period.
