Ian drives Bridget home and attempts to force his way inside her home, but she punches him. As he's leaving, Ian sees Bridget beckoning him to come. The sight is revealed to be a trick by the Leprechaun, who has given a running lawnmower her appearance. Ian is killed as he goes to kiss what he thinks are her bare breasts, actually the spinning mower blades. Cody visits Bridget and gifts her flowers, and they reconcile. The flowers cause Bridget to sneeze three times, and the Leprechaun suddenly appears to claim her. He escapes with Bridget, but loses one of his gold coins, which lands in Cody's possession. The Leprechaun takes her to his lair and plans to make her his bride, but realizes a coin is missing. He leaves to get the coin back. Since Cody left the flowers behind, he is considered a prime suspect in Ian's death and Bridget's disappearance.Cody returns home and consults a book with Morty. They learn about the Leprechaun's search for a bride and that cast iron is his one weakness. The Leprechaun suddenly attacks, demanding his coin back. Cody makes a deal to give the coin in exchange for Bridget, unaware the Leprechaun plans to double-cross him. Morty intervenes and they escape to a bar celebrating St. Patrick's Day. Morty notices the Leprechaun at the bar and challenges to a drinking contest, reasoning with Co dy that Bridget can't be harmed as long as the Leprechaun is with him. Morty wins the contest, but the Leprechaun escapes. He sobers up at an espresso bar, killing an obnoxious barista. Remembering the Leprechaun's weakness, Cody and Morty go to the go-kart track and empty the facility's cast iron safe, intending to capture the Leprechaun inside.
