St. Patrick's Day 2011

 Lorin says: I AM BEING BLINDED BY ALL THE GREEN x_x; When will there be a day for orange?!

On March 14th, Four Leaf Clovers began appearing in Explore (Fields only), Cooking and Dailies. On March 18th, a News post announced the Seasonal Shop was open and that Four Leaf Clovers were the new Exchange Item used as currency. Nine St. Patrick's Day customs were also given away in a free raffle. As of March 22nd, Clovers were still available and the Seasonal Shop was still stocking the pets.

Lucky Clover Potions
During this event, it is notable that based on the prices of all the pets, the expected value of a Lucky Clover Potion was 9.9 Clovers. Since the Lucky Clover Potions sold in the shop for 7 Clovers, many players chose to buy Lucky Clover Potions instead of directly buying pets.
