Lost City

Once on the new land, find the Kabuki Monument and take this peculiar stone home! You will need to upgrade this monument. Each upgrade stage will give you a wise hokku poem. After the last stage you will get to turn the monument into an impressive heap of valuable gifts.

Find it near the entrance to Lost City, take home and upgrade to transform into a mountain of gifts. 

(Looks just like a rock, check your Airship or storage if you can not find it)
