Other Versions
In other versions of the tale, it appears to lone men working in the jungle when they are thinking of women they left behind in their hometown or simply when they talk to their work mates about wanting to be with a woman. Later on, a woman would appear to them in the likeness of an unknown, beautiful and desirable woman, or a loved one, and try to lure them into the forests so it could then reveal their animal-like features and devour them or just mangle them, leaving their wretched bodies for their companions to find.

In another version told in the peacock mountains, the woman would appear to men in the jungle who were lonely and willing to be unfaithful with their companion. Stories often claim that several men would take act in unveiling their selves to this ghost woman, and she would let all the men have sex with her. She would then devour their body parts, though it is most often noted that she would tear each mans genitals off with her hand or mangle them beyond use ever again, in order to punish them. Although many men in the jungle are said to have encountered La Sayona, most of them still have their genitals. It is said that she also has many strange diseases, and that she sometimes gives them to men, making their penises swollen with blisters and boils. Their wives find these boils and can assume that their husbands have had an encounter with La Sayona, effectively informing her that her husband has been unfaithful.
