Oriental Trader Mini World Change/Spoiler

Messages
World Board: ''Oriental ships sighted! A trader for exotic creature products may currently be visiting Carlin, Ankrahmun or Liberty Bay.''

Towncryer: Hear ye! Hear ye! What a lucky and beautiful day! Visit Carlin, Ankrahmun, or Liberty Bay. Yasir, the oriental trader might be there. Gather your creature products, for this chance is rare.

Method
The merchant Yasir will drop anchor off the harbour of one of these towns: Ankrahmun, Carlin or Liberty Bay. During this time you are able to sell almost all Creature Products to him.

Say ariki or trade to Yasir to get the achievement Si, Ariki!.
