Look for Radioactive Carp during Spring / Summer / Fall / Winter at The Sewers. Time: Any. Weather: Any.
Chase Radioactive Carp when Spring / Summer / Fall / Winter is active, the Any time window fits your day, and you do not need to wait for special weather. For planning, treat it as a collection or selling target rather than a bundle emergency.
Skip the trip when you need the day for crops, mining, tool upgrades, or a higher-priority bundle fish. The location is The Sewers, so it is best chased when travel time will not interrupt a stronger plan.
