Justice League (2001)
S04E15 Terrible Leprechaun
Episode Overview
In this episode, we meet twin leprechauns: one is kind-hearted, while the other is quite unpleasant. The mischievous leprechaun has his sights set on the treasure hidden under a defense installation in the Irish Sea. Meanwhile, his good-hearted brother is determined to thwart his sibling's plans to seize the gold. In a familiar twist, clips of Morton and Kowalski stuck in an underwater cave make an appearance from earlier episodes. As for why this episode didn't air on St. Patrick's Day, that remains a mystery.
