Lighthouse Island: Find the Keeper, Get Keys and Leave

Work through the departure checklist and resolve the remaining steps before moving on.

Updated September 7, 2026

Start here

Finish the Keeper’s Shell exchange, collect Boat Keys, then buy Radar and use the wooden boat’s helm. Forest is the green destination.

Use the lighthouse door and the Keeper

The yellow Beer hangs on the lighthouse door. Aim at its $12 purchase prompt, buy it and carry the full bottle to the black-hatted Keeper.

Give him the Beer and take the Empty Beer Can. Select that bait to catch Spider Crab; the complete fight route is linked below.

Return Spider Crab’s red Shell to the Keeper.

When he offers the keys, aim at Take Boat Keys and press E.
