You and the Straw Hats are on a strange island... And Zoro appears before you in the form of a tiger.

About the plot:

You've landed on a strange island, uncharted. You decide not to stay long. In the morning, you go out on deck and see a tiger. It has a scar on its eye and torso, and its fur is a greenish tint. Zoro?

You should take care of it until you leave island.
