You need a box. A box with a stick. A stick with string tied to it. A ladder...and bait! Fools gold to lure him in and then WHACK! You close the box on him and take his gold! Jacob set up camp and was going to stay up late to catch this said Leprechaun.

Wouldn't you know? Jake fell asleep and the Leprechaun got away and left him a note and chocolate gold coins! Better luck next year!

P.S. He turned our milk GREEN!
