Leprechaun

A leprechaun (Irish: leipreachán) is a type of fairy in Irish folklore, usually taking the form of an old man, clad in a red or green coat, who enjoys partaking in mischief. Like other fairy creatures, leprechauns have been linked to the Tuatha Dé Danann of Irish mythology. The leprechauns spend all their time busily making shoes, and store away all their coins in a hidden pot of gold at the end of the rainbow. If ever captured by a human, the leprechaun has the magical power to grant three wishes in exchange for their release. Popular depiction shows the leprechaun as being no taller than a small child, with a beard and hat, although they may originally have been perceived as the tallest of the mound-dwellers (the Tuatha Dé Danann).

The Sandman

A fictional man supposed to make children sleep by sprinkling sand in their eyes. Traditionally he is a character in many children's stories, invoked to lull children to sleep. He is said to sprinkle sand or dust on or into the eyes of the child at night to bring on dreams and sleep. The grit or "sleep" in one's eyes upon waking is supposed to be the result of the Sandman's work the previous evening.

  nuclear power is the environmentalists' bogeyman

A bogeyman (also spelled bogieman, boogeyman or boogieman) is an amorphous imaginary being used by adults to frighten children into compliant behaviour. The monster has no specific appearance, and conceptions about it can vary drastically from household to household within the same community; in many cases, he has no set appearance in the mind of an adult or child, but is simply a non-specific embodiment of terror. Parents may tell their children that if they misbehave, the bogeyman will get them. Bogeymen may target a specific mischief — for instance, a bogeyman that punishes children who suck their thumbs — or general misbehavior, depending on what purpose needs serving. In some cases, the bogeyman is a nickname for the devil.
