Check Perfection at the tracker in Qi's Walnut Room on Ginger Island. It is separate from Grandpa's evaluation and covers shipping, fishing, cooking, crafting, friendship, skill levels, Stardrops, Golden Walnuts, monster goals, four obelisks, and the Gold Clock.
This checklist orders the remaining work efficiently: what to finish on Ginger Island, which friendships need birthday gifts you keep missing, and how the walnut tracker shrinks the last hunt.
