The Irish brought some stowaways with them when they came across the Atlantic. And every now and then you hear reports of Leprechauns outside their native element.
I know most you grew up thinking of Leprechauns as vaguely amusing fussbudgets worried about kids stealing their lucky charms, but Mama Mudskipper came from a long line of Irish women and knew the old stories.
Leprechauns are nothing to laugh at. They can be mean and vindictive if provoked. Which is why the people in this video ought to show a little more respect if they don't want to end up on the wrong side of the rainbow.
