A man visiting the Fairyground is rather flustered after misplacing his diary once again.
This errand is available to complete after completing Errand 080.
The traveling man from before has apparently reached the Fairyground and has naturally lost his diary again. Head to the Crab Cave on the northwest side of the island, and once you're inside, inspect the wooden trunk on the east side of the room to retrieve the traveler's diary once again. Bring it back to the man to complete the errand.
