“One wails. One bites. One beguiles. La Llorona, La Muelona and La Siguanaba await in the dark. Three legends La Muerte wants you to meet, but you’ll wish you never did”.
La Llorona obviously wails. But for the other two, it's a bit unclear - according to some preliminary googling, both La Muelona and La Siguanaba beguile men, luring them from the path, and then biting (leading men astray and biting either with sharp teeth or a horse head).
I have loved Monstruous 1 and Monstruous 2 in Hollywood, so have no doubt Monstruous 3 will also be good, but I'm curious how they will distinguish these three sufficiently.
