Little Ireland is a neighborhood located in downtown Dimmsdale where Irish people can be free to express their culture and traditions.
During Leprechanuka, Cosmo brought his family to a shop there called Lucky Potato and told them the story of Leprechanuka, and they enjoyed a nice meal of four leafed clovers together. Then, Denzel Crocker arrived to catch leprechauns (after he chose them as his new obsession), and managed to capture Cosmo, who was dressed as a leprechaun. He demanded a pot of gold and Cosmo gave him one, but it was the McPunchies Clan's pot of gold, and they took Wanda and Poof captive until Cosmo and Timmy brought it back.
Like Ireland, everything in Little Ireland is green, including the stoplights, the butterflies that fly there and even the sky. The shops are decorated with four leaf clovers and pots of gold. One of the shops called Lucky Potato, has a potato holding a horseshoe on its roof.
