To unlock the Grill in How to Fish, the most detailed walkthroughs direct you to speak with the Grill Master on Island 3, buy a Standard Boss Lure, defeat the Blue Shark it summons, and bring the shark’s body back to the Grill Master. The lure is reported to cost $280 and be consumed when used. Then cook catches carefully: guides recommend removing them at about 1.5x value, before they burn.

How to unlock the Grill on Island 3

The detailed route reported by gameplay guides is to deliver the Blue Shark’s body to the Grill Master beside an unlit grill. The precise relationship between this step and the island’s Tourist questline is not consistently described, so treat this as a guide-reported route rather than a confirmed official quest sequence. [NerdsChalk; TheGamer]

  1. Find the Grill Master. Go to Island 3 and speak to the NPC standing by the unlit grill.
  2. Buy the correct lure. Purchase the Standard Boss Lure from the nearby shop. NerdsChalk reports a price of $280; the lure is consumed on use. Do not substitute the cheaper Standard Lure: the walkthrough says it will not summon the Blue Shark.
  3. Equip and cast it. Cast the Boss Lure into deep water to trigger the Blue Shark encounter.
  4. Defeat the shark. Use the fight advice below, then pick up its body.
  5. Return to the Grill Master. Bring the shark’s body to the NPC and use the lighter to start the grill.

Some coverage frames the Grill as part of Island 3 progression involving the Tourist request chain. If returning with the shark does not light the grill, continue the island’s Tourist quests and check back with the Grill Master. The available guides do not establish a definitive ordering for every prerequisite. [How to Fish Wiki]

How to beat the Blue Shark

The Blue Shark is described as an optional mini-boss tied to the Grill objective, not the Island 3 story boss. The Pufferfish is the story boss encountered later through the Tourist quest, according to the cited walkthrough. [NerdsChalk]

Yojaro 4Pack Silicone Suction Phone Case Mount, Silicon Adhesive Smartphones Stand Sticky, Hands-Free Phone Accessories Holder for Selfies and Videos (Black & White & Translucent & Light Pink)
  • 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
  • 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
  • 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
  • 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
  • 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)

Keep moving between its charges

The guide describes the shark as fast and prone to lunging. Strafing instead of standing still, firing between charges, and using Shift to dash when cornered are its recommended tactics. [NerdsChalk]

Choose the weapon you can use reliably

The same guide presents an upgraded shotgun as forgiving at close range, while an upgraded SMG can work if you land accurate shots. These are guide-reported options, not a proven universal best build; use the weapon you handle most confidently.

Apple EarPods Headphones with USB-C Plug, Wired Ear Buds with Built-in Remote to Control Music, Phone Calls, and Volume
  • SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
  • HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
  • BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
  • COMPATIBILITY — Works with all devices that have a USB-C port.
  • INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.

Bring food if you want a reported mid-fight recovery option

NerdsChalk suggests catching ordinary fish before using the lure, dropping them on the sand with Q, and eating one during the fight to recover health. This is a reported tactic, not an independently verified mechanic. Keep ordinary catches separate from the shark or any quest item.

How to cook fish without burning it

Once the grill is lit, place a catch on it and watch its displayed value or multiplier. Gameplay guides recommend removing it at about 1.5x value; leaving it too long can burn it and reduce its value. Use the on-screen inspect prompt to check the item, since guides differ on the inspection control and controls may vary by language pack. [NerdsChalk; How to Fish Wiki]

Can you undo cooking on weapons or tools?

A guide reports that patch 1.0.10, dated August 27, 2026, added a way to clear a cooked state from tools and weapons by dipping them in water. That claim is secondary-source reporting, not confirmed here by an official patch note. An older guide says cooking cannot be reversed, so the accounts differ by reported version. If this matters to your run, check the behavior in your current game version before relying on it. [How to Fish Wiki; NerdsChalk]

What to do if the Grill remains unlit

  • Confirm you bought the Standard Boss Lure, not the Standard Lure, and used it in deep water.
  • Make sure you returned to the Grill Master with the Blue Shark’s body and used the lighter as described by the walkthrough.
  • If the grill still does not light, progress the Island 3 Tourist questline and revisit the NPC; published guides differ on how that progression fits into the unlock.

These steps and mechanics come from secondary gameplay guides published or updated in August 2026, not official game documentation. Prices, controls, quest order, and mechanics may change with updates, so use the current in-game prompts if they differ.
