Probably not many, for the Tsuchigumo version.How many babies do spiders have at once anyway?
Female spiders deposit as many as 250 eggs into a sac of silk. These sacs are often brown in color and are flask-like in shape. Females produce up to 17 of these sacs during a lifetime, resulting in more than 4,000 eggs over the course of the spider's life.
But how about the second one? The third one? Or even the fourth one!!?
Yeah, the fact that it was just her and her mom living together does suggest that she probably didn't have any siblings, at least not of her age.Probably not many, for the Tsuchigumo version.
