Swoolurk carries its head in its hands since its body is full of ultrasonic waves that would give it constant headaches otherwise. Anyone who takes one of its heart-shaped seals from its body is cursed with eternal misfortune.
It is said that Swoolurk were ordered to protect people and Pokémon by the ancient people who made them. Anyone who comes into contact with the ultrasonic waves emitted by a courting male experiences a positive mood shift.
