Beer Quest: How to Fish Beer and Catch the Spider Crab
How to fish beer: buy the Beer Can at the Lighthouse, give it to the Keeper, use the Empty Beer Can on Spider Crab, and return the meat for boat keys.

To complete the How to Fish beer quest, buy the Beer Can at the Lighthouse, give the full can to the Lighthouse Keeper, and take the Empty Beer Can he returns. Use the empty can as the special bait for Spider Crab, then bring the Spider Crab meat back to the Keeper for the boat keys. The green Forest route appears after the hand-in and radar step. The important distinction is that the beer starts a quest chain; it is not the normal lure for an early fish.
What the Beer Can actually starts
The opening quest is a short item exchange followed by a boss encounter. The collected materials consistently record the sequence as Beer Can to Lighthouse Keeper, Empty Beer Can to Spider Crab, then Spider Crab meat back to the Keeper. Each item has a different job, so keeping the names separate is more useful than memorizing only the word beer. If the inventory shows the full can, the quest has not yet reached the summon stage.
This quest also teaches the progression rule used by later islands. A boss can be defeated without the next destination appearing if its named drop has not been returned to the requesting NPC. The Spider Crab meat is the hand-in object in the collected route, while the Empty Beer Can is the summon bait. Do not sell, cook, or abandon either item while the Lighthouse route is active.
Earn enough money at the Lighthouse
The collected early-game guides describe clams as a simple way to earn opening cash. They also record a Basic Fishing Rod for $3, a Free Lure, and a Hotdog Lure for $1. Use the ordinary catches and clams to build the money needed for the Beer Can and radar rather than spending every early dollar on optional gear. These values come from the collected source snapshot and should be checked against the current shop if a patch changes them.
The Lighthouse regular fish are a separate part of this preparation. The all-fish material records Rock Crab on Free Lure or Hot Dog, Shrimp on Free Lure, and Lobster on Hot Dog. Those catches can fund the quest, but they do not replace the Beer Can or Empty Beer Can. If a catch looks like a crab, inspect its name before assuming it is the Spider Crab boss.
A sharpened knife is also recorded as dealing 20 damage after using the anvil. It can help with early combat tests, but the collected route does not require you to use it as the only Spider Crab weapon. Treat it as a low-cost preparation option and preserve enough money for the quest item. The route is easier when the inventory contains the correct bait and the player still has a way to deal ranged or close damage.
Give the full can to the Keeper
Find the Lighthouse Keeper near the opening boat and hand over the full Beer Can. The quest chain is looking for the can as a delivery item, so the relevant action is the Keeper conversation rather than a cast into the water. After the exchange, check the inventory for Empty Beer Can. Seeing the empty item is the confirmation that the first half of the quest registered.
Do not equip the full can as if it were the Spider Crab bait. The special bait is the empty can returned by the Keeper. If the hand-in does not trigger, walk back to the Keeper with the can in the inventory and interact again before buying another copy. The collected sources do not establish a separate hidden character or code for this step, so do not search for one.
Once the Empty Beer Can appears, prepare for the boss rather than casting immediately. Select the item on the fishing rod, make sure your combat weapon is ready, and leave room in the inventory for the meat and other drops. The summon item is tied to Spider Crab, not to the normal Rock Crab listed in the fish checklist. This small preparation prevents a lost cast from being mistaken for a bait or map problem.
Use Empty Beer Can on Spider Crab
Equip Empty Beer Can and cast it in the Lighthouse water as the collected quest guides describe. Spider Crab is the first and simplest boss encounter in the recorded route, but it still has a charge that can stun or punish a player standing too close. Keep a little space, watch the boss's approach, and be ready to move after each attack. The fight is an objective step, not a regular fishing catch.
The collected boss sources describe a white bar under the health bar that represents the boss's escape window. Damage the Spider Crab before that bar empties, and avoid letting a charge catch you in place. One guide records a short sequence of possible hits and says two or three comfortable openings can be enough, but the exact timing depends on the player's weapon and build. Treat the hit count as source guidance rather than a universal requirement.
The safest rhythm is to bait the charge, sidestep or move out of its line, and attack during the recovery window. Do not stand directly in front of the crab and wait for the stun to happen. If the boss misses, use that moment to land damage and then reset your distance. The collected material does not require a secret weapon name for this first fight, so focus on the charge pattern and escape bar.
Return the Spider Crab meat
After Spider Crab dies, collect the meat and any named quest drop rather than leaving the arena immediately. The Beer quest chain specifically records Spider Crab meat as the item returned to the Lighthouse Keeper. Ordinary Rock Crab, Shrimp, or Lobster catches cannot satisfy that hand-in. Keep the quest item intact while walking or boating back to the starting character.
Give the meat to the Keeper and complete the dialogue. The collected progression sources connect this exchange with the boat keys, which change the opening island from a trapped starting beach into a travel point. If the keys do not appear, check that the item in your inventory is the Spider Crab meat and not a normal meat chunk. A successful conversation is the real checkpoint for the next map step.
The quest does not finish at the moment the boss health reaches zero. This is the same hand-in pattern used by the Giant Piranha skeleton, Pufferfish Fin, and later bird or whale items. The islands guide uses the Beer quest as the first example of that pattern. Remembering it here makes later missing radar dots much easier to diagnose.
Buy the radar and find Forest
The collected early guides record the radar at $10. Buy it after the boat keys are available and use it to read the next destination rather than sailing by guesswork. The map material identifies Forest with a green dot and places it northwest in the collected route directions. If the dot is not visible, confirm the Keeper hand-in and the radar before leaving the Lighthouse.
The map guide records the full color sequence: green Forest, yellow Desert, red Rocks, and pink Volcano. The Beer quest only opens the first of those markers, so do not expect every island to appear immediately after Spider Crab. The route continues through the Giant Piranha and Pufferfish chains before later colors unlock. A missing green dot is therefore an opening-quest problem, while a missing yellow or red dot belongs to a later hand-in.
Once Forest is visible, stock the lure tier needed for its normal fish and keep any boss bait separate. The all-fish sources list Free, Beginner, and Hot Dog options for Forest, while the Giant Piranha uses modified bait from the leech step. The Beer Can chain has already done its job and should not be reused for a normal Forest catch. This separation keeps the inventory legible as more special items accumulate.
Troubleshoot the beer chain
If the Keeper does not accept the full can, check that you bought the Beer Can at the Lighthouse and are speaking to the correct opening NPC. If the Empty Beer Can is missing after the conversation, interact again with the Keeper before attempting a boss cast. If Spider Crab does not appear, confirm that Empty Beer Can is equipped instead of the full can or a regular fish lure. These checks follow the collected item chain without inventing another trigger.
If the boss died but the boat keys are missing, search the water and shore for Spider Crab meat. The sources describe loose drops and a separate hand-in, so a cleared health bar is not enough. Return the meat to the Keeper and finish the dialogue, then check the radar for green Forest. If a current build uses a different item label or interaction, record that detail as Pending confirmation rather than replacing it with a guessed code or reward.
The quest is deliberately compact, but it establishes the whole game's rhythm: earn money, buy a named item, exchange it with an NPC, use the returned bait, recover a named drop, and hand it back. Once the Beer Can, Empty Beer Can, Spider Crab meat, boat keys, and radar are understood, the later island chains are variations on the same structure. Keep the beginner guide open for the opening economy and the islands route open for the next hand-ins. No part of this chain requires an unlisted character name, redeem code, or hidden numeric shortcut.
