Whenever you collect 10 points, C.J. will reward you with a random fish-related gift, ranging from clothing to furnishings. These items are exclusive to the event and cannot be re-purchased through Nook Shopping if you sell them.
The best way to grab fish quickly is to have a bunch of Fish Bait ready to go. Once the timer starts, just waddle up to the closest body of water, toss in the Fish Bait, and keep reeling in the fish that show up. (You can make Fish Bait out of Manila Clams dug up on the beach with your shovel.) Don’t worry if you have a full inventory — any fish you catch will instantly go to the safety of C.J.’s cooler in front of www.lolga.com Resident Services.
