“Female sloths find their mates when they’re ready to breed, and they do it by beckoning mates to come to them. A female sloth in heat screams to attract males, which will journey toward the source of the noise in pursuit of a mate. Once males get there, they may fight each other for her affections — sloths have been found to be territorial, and some bear scars from mating-related scuffles.”

Which is almost exactly how I landed Manfried, give or take.
