Evidence boundary for Spider Crab
The supported record identifies Spider Crab as a legendary boss associated with Lighthouse (Island 1). KeenGamer complete walkthrough & all fish locations (per-island bait tables), checked 2026-08-26.
Exact spawn odds, health, damage, sale value and map coordinates are deliberately omitted unless a stable source verifies them. A missed encounter is not proof of a hidden timer or a bug; confirm the listed lure and story access before changing anything risky.
