How to Unlock Sunny Shores
Step-by-step guide to unlocking Sunny Shores in Cat Mail Co through the Summer Room upgrade and destination expansion.
What You Need
Sunny Shores unlocks through the Summer Room upgrade — the second-highest priority investment in our Progression guide. You need sufficient currency from processed parcels and successful boat departures to purchase the upgrade. No special quest or hidden trigger is required beyond earning enough postal income.
Focus on correctly processing every parcel during your first days to build upgrade currency quickly. Stamp bonuses from decorative stamps accelerate earnings. Avoid costly rework from mislabeled mail that returns damaged.
The Unlock Process
Once you purchase the Summer Room upgrade, Sunny Shores appears as a routing destination on your map and in stamp mode. The Summer Room also provides additional physical workspace in your post office — a dual benefit of more space and higher-value delivery routes.
After unlocking, create a dedicated Sunny Shores shelf on the right side of your processing area. Route all Sunny Shores parcels there before evening boat loading to prevent mixing with Port Windy or local deliveries.
