Once you’ve completed this behest around five times, you should reach level 10, unlocking a similar quest on the next island. Head over to the dock and take note of the board just before it – a map of the neighboring islands, complete with their suggested level ranges – and speak to the Boat Dealer. Select the free Dingy, jump into the seat, and use your usual movement keys to sail away to the island with the jungle silhouette. Those tall trees will be your home for a while.
Sailing to your next destination is as easy as tapping the compass icon on the left of the screen. No matter where you are, tracking the quest it brings up will put up a handy marker on your screen, complete with distance. Head in that direction to find a level-appropriate quest to grind until you’re notified of another.
