 In traditional tales the blue men have the power to create severe storms, but when the weather is fine they sleep or float just under the surface of the water. They swim with their torso from the waist upwards raised out of the sea, twisting and diving in a similar way to a porpoise. To amuse themselves the creatures play shinty when the skies are clear and bright at night. They are able to speak and converse with mariners and are especially vocal when soaking vessels with water spray, roaring with laughter as vessels capsize.
