Known as a biting fairy, it is often mistaken for a real fairy, even though it is a completely different species. It has a miniature human form, but it is covered with black hair and has an extra pair of hands and feet. They like the colder climate - northern Europe and America. They lay up to 500 eggs at a time and bury them in the ground. The young hatch in two to three weeks. The treadmill has two rows of sharp and poisonous teeth - after a bite, it is advisable to apply the appropriate serum.
