Leprechauns like gold and shiny objects. Leprechauns also like to eat traditional Irish food, such as stew, soda bread, potatoes and bacon. They also enjoy drinking Guinness, claims CityBeat.
Leprechauns keep a tight grip on their pots of gold, but if a leprechaun is captured, he will exchange it in return for his freedom. When caught, a leprechaun will escape as soon as his captor is no longer looking at him, and he will use all kinds of tricks to avert the captor's eyes. Leprechauns also like random acts of kindness, as told in a story of a nobleman who offered a leprechaun a ride on his horse, and afterwards the leprechaun filled his castle with gold.
