“To dig up the Lakiaro, you will have to play our newest minigame. If you find a Lakiaro, you can equip one of our new hoes (Manos Hoe, Dostter Hoe, or Dostter Steel Hoe) and interact with the Lakiaro to start the minigame. The object of the minigame is to either find all of the roots of the Lakiaro, or dig up all of the dirt around the Lakiaro. If you are too rough while digging for the Lakiaro, you may damage it. Simply left or right-click to dig up the Lakiaro. You will get a better reward the less damaged the Lakiaro end up. Besides, if you manage to dig up a perfectly intact Lakiaro root, you will be able to sell your reward for an exorbitant price!”
