Island Trader records for 10 Golden Walnut unlock after Island Farmhouse, fixed stock, rotating stock, Taro Tubers, Pineapple Seeds, Banana and Mango Saplings, Golden Coconut trades, recipes, Galaxy Soul last-day stock, and barter resource planning.
Unlock After Island Farmhouse
Unlock / 10 Golden Walnuts, Island Farmhouse prerequisite, and Island North shop route
The Island Trader unlocks for 10 Golden Walnuts after the Island Farmhouse has been purchased. Treat it as a mid-island economy unlock, not the first parrot purchase, because Island West and the farmhouse must already be online.
Tropical Crop Seed Route
Crops / Taro Tubers, Pineapple Seeds, Taro Root, Bone Fragments, and Magma Caps
The fixed stock turns island and Volcano materials into crop scaling: Taro Tubers cost 2 Bone Fragments, Pineapple Seeds cost 1 Magma Cap, and Warp Totem: Farm or Tropical TV consume Taro Roots.
Banana and Mango Saplings
Fruit Trees / 5 Dragon Teeth, 75 Mussels, Island Obelisk, Leo gifts, and year-round island fruit
Banana Saplings cost 5 Dragon Teeth, while Mango Saplings cost 75 Mussels. These trees produce year-round on Ginger Island and support Island Obelisk planning, Leo gifts, tropical cooking, and fruit tree collection routes.
Golden Coconut Loop
Loot / 10 Coconuts after cracking the first Golden Coconut
After the first Golden Coconut has been cracked, the Island Trader can barter Golden Coconuts for 10 regular Coconuts each. This creates a controlled way to chase golden coconut contents when palm-tree or artifact-spot luck is slow.
Recipes and Crafting Stock
Recipes / Banana Pudding recipe and Deluxe Retaining Soil recipe
Two fixed recipe trades matter for completion and farm layout: Banana Pudding costs 30 Bone Fragments, and Deluxe Retaining Soil costs 50 Cinder Shards.
Rotating Decor and Hats
Rotating Stock / Even days, weekdays, and island resource barter
The trader's rotating stock changes by day: Tropical Chair on even days, hats and island decor on weekdays, and beds or rugs on weekend routes. Plan cosmetics around resource availability instead of checking randomly.
Galaxy Soul Last-Day Route
Combat / Last day of season, 10 Radioactive Bars, and 50 dangerous monster kills
Galaxy Soul appears at the Island Trader on the last day of a season after killing at least 50 dangerous monsters. Each costs 10 Radioactive Bars, making it a late combat and radioactive-material route.
Barter Stockpile Plan
Storage / Cinder Shards, Dragon Teeth, Bone Fragments, Mussels, island fish, fruit, and crops
Because the Island Trader does not accept gold, the real route is storage discipline. Keep a labeled island barter chest for Bone Fragments, Cinder Shards, Dragon Teeth, Mussels, Coconuts, Ginger, Taro Roots, island fish, tropical fruit, and Radioactive Bars.
