Recording the Island's Magnetic Field

- **Villagers:** "Why?" - **Villagers:** "This log pose has to record this island's magnetic field, and the recording time varies for each island." - **Villagers:** "Before we can move on to the next island!" - **Villagers:** "There're some islands that take only a few hours to record, while some take even a few days." - **Villagers:** "T-then even if we come to a horrible monster island that we want to run away from, It's possible that we'll have to stay on it for several days...!?"
