This is a Leprechaun Trap. My 1st grade son made it just before spring break. It's a kleenex box with a ladder where the leprechaun can climb up, and fall into the hole. There are gold coins at the top to attract them, and the sign says do NOT enter, because leprechauns always do the opposite of whatever you say. This was totally my son's idea. Iit's fun having a 7 year old.
Happy St Patricks Day everyone.
