So, which comes first, the Leprechaun or the egg? Okay, no one really cares, but it's an interesting question. Included in this kit you'll find some Leprechaun Eggs. Unfortunately, they won't hatch into real Leprechauns (FedEx won't let us ship real leprechauns), but these eggs are just like the real thing. The coolest thing is that the eggs actually become invisible in water... a perfect way for Leprechauns to hide. You'll uncover the secret and even use a special trick to find their hiding place.
