Facts and route notes
Category: Upgrade
Focus: 5 Golden Walnuts and island mail access
Checklist: Buy the mailbox when island stays are long enough that mainland mail trips are annoying. Use it before multi-day Volcano, farming, or Golden Walnut cleanup sessions. Remember this upgrade is also required before the Farm Obelisk can be built.
