Kawauso

'Kawauso were mischievous spirits that originated from the Realm of Animals, Chikushō-dō. They commonly took on the form of river otters and delighted on playing pranks on humans, mimicking people's voices and reveling in the ensuing confusion. Some especially tricky youngsters appeared as attractive humans, flirting with travelers then running away in a fit of giggles. No harm would come from ignoring them.
