What are the St. Patrick's day artifacts?

I just realized there was a St. Patricks's day event and got an "Emerald Idol" for that. It looks like the same as the Christmas and Valentines events- 5 themed artifacts and then the reward is some kind of hat.

What are the artifacts for the St. Patrick's event?


I was lucky and found them all quickly without much repeating. They are

  • Rainbow
  • Pot O' Gold
  • Leprechaun Boots
  • Four Leaf Clover
  • Emerald Idol (ha ha!)

The reward is another hat, a green Leprechaun-type one.
