2. Choose "Yes" and board the boat. Kapp'n will then sail you to the island.
3. Explore the island. You can catch bugs, fish, and dig up fossils on the island. You can also talk to any animals you find there.
4. When you are ready to return to your own town, talk to Kapp'n again. He will take you back for free.
Note: You can only visit the island once per day. If you try to visit again on the same day, Kapp'n will tell you that he is too tired to take you.
