The eastern end of Ginger Island is home to an NPC named Leo, who will move to Stardew Valley once his heart level reaches six. One of the main benefits of finding Leo, however, is his talking parrot, who will disclose how many Golden Walnuts remain to be found in each area. In the jungles of the island's eastern end, you can also find the Gem Birds shrine. Completing a puzzle in the shrine will net you five Golden Walnuts, so it's a worthwhile trip.
