A rodent with flesh webbing between feet, similar to the added two orifices of a service provider in dynastic China (「five orifices of child, rat」). A rodent arrogant enough to attempt flight as do birds and chicks, the euphemisms of females for sex (actually, the squirrel glides well, as would a skilled service provider):「flying」is a worldwide euphemism for「fucking, sexual reproduction.」A「rodent that can impede, resist」the progress of a rival:
「From winter to early summer the males compete for females. During mating, after ejaculation, the male produces a sticky protein called a coitus plug from his penis which becomes firm and blocks the female's vagina. This may stop semen from leaking out and heighten the chances of fertilization. It also prevents other males from mating with the same female. However males can use their penis to remove the coitus plug」

「Rat-like with five orifices」refers to both the rodent with webbing between its limbs, and very young child service providers available for short-term rentals at the shaman's cave 'o wonders with pulverized feet: as depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis ostensibly to lower the risk of contracting a sexually transmissible disease or infection that often occurred when performing coitus within some sort of mucous membrane system of a female service provider, and, to gain hand-control over the pressure applied to the foot meat surrounding a weakened penis that functioned as a living cockring.
「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)

「Viewing women as commodities [see 品, the original three orifices in a glyph designed prior to the advent of foot busting] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」
