Bundles are donations to the Junimos given via golden scrolls inside the Community Center. When a bundle is complete, the Junimos offer you a reward. When all bundles for a particular room in the Community Center are complete, the Junimos grant a special reward that sometimes benefits the entire community.
Bundle rewards are given immediately, but rewards for completing all bundles in a room are given at the end of the day via a cutscene depicting the Junimos fulfulling the reward.
A few bundles display more items than there are slots to fill (e.g., Artisan Bundle: 12 items, 6 slots to fill). In this case, you can choose which of the shown items you want to use to fill the bundle. You do not have to use all shown items, only enough to fill the slots.
Completing all bundles restores the Community Center back to brand new and unlocks the "Local Legend" Achievement. The day after all bundles are complete, there will be a cutscene showing the grand re-opening of the Community Center. (This event is triggered by entering Pelican Town Square.)
If you opt to purchase a JojaMart Membership, the Community Center is turned into a Joja Warehouse instead. After this happens, the bundles will be completed by the Joja Corporation for a fee given to Morris, the local JojaMart manager, through the Joja Community Development Form.
Golden Scroll
There are a total of 6 rooms and 30 bundles to complete in the Community Center. In the Joja Warehouse, there are 5 rewards to purchase (the "Friendship" reward is not available).
Bundle Progress can be checked at any time by clicking on the Golden Scroll icon at the top right of the Player Menu (above the Garbage Can and "organize" icons).
Travelling Cart Availability
All items required for bundles have a small chance of appearing in the Travelling Cart stock, except for the items listed below. These items will never be sold at the Travelling Cart:
The Crafts Room contains the first group of bundles available. Completing all Crafts Room bundles repairs the bridge east of The Mines, giving you access to the Quarry.
The Pantry appears after completing one bundle. Completing all Pantry bundles will restore the dilapidated Greenhouse on your farm, making it available to grow Crops and Fruit Trees year-round.
The Fish Tank appears after completing one bundle. Completing all Fish Tank bundles will remove the Glittering Boulder to the left of The Mines entrance. Willy will also give you a Copper Pan that can be used to collect metal ores and other items from bodies of water.
Note: It may not be possible to finish the Specialty Fish Bundle before finishing the entire Vault section, as you need access to the Desert to get a Sandfish, unless it becomes available at the Traveling Cart.
The Boiler Room appears after completing two bundles. Completing all Boiler Room bundles repairs the Minecarts, allowing you to fast travel between distant locations.
The Bulletin Board appears after completing three bundles.
Completing all Bulletin Board bundles improves the player's friendship rating with every non-datable villager by two hearts (500 points).
The morning after, Mayor Lewis will send a letter saying that packages containing items posted about "years ago" on the community center bulletin board have been appearing in villagers' homes. He says the packages are all addressed from "your farm." He expresses his gratitude and says "all of us in town are delighted!"
The Vault becomes available after completing four bundles. Pressing the large "purchase" button will purchase the bundle and deduct the gold from your total.
Completing all Vault bundles costs data-sort-value="42500">42,500g, and repairs the Bus Stop. Taking the Bus grants access to The Calico Desert.
