Mechanics / 4 days plus 3 fish, 15-day fallback, before 11 PM, and 1% bubble upgrades
Fish Frenzies can start before 11 PM after either 4 days plus 3 caught fish or 15 total days. When ordinary bubbles spawn in eligible areas, there is a 1% chance for that bubble spot to become a frenzy.
Facts and route notes
Category: Mechanics
Focus: 4 days plus 3 fish, 15-day fallback, before 11 PM, and 1% bubble upgrades
Checklist: Catch at least 3 fish by early Spring if Fish Frenzies should be possible from day 4 onward. Watch the location message so travel time does not erase the best part of the window. Ignore impossible festival days except Desert Festival, Trout Derby, SquidFest, and Night Market.
