In Japanese folklore, Amikiri are yokai (demons/spirits) which cut people's mosquito nets (in many parts of the world, mosquito nets are put up to keep the biting bugs out on hot summer nights). The Amikiri is said to be a small creature that resembles a combination of lobster, snake, and bird. It has crab claws and a long tail. It also cuts fishing nets and laundry hung out to dry. Evidently, it's a low-tech version of the Gremlin.
