Larry Fish It Guide, Location & Where to Find!

Larry is one of the most important NPCs in Fish It Roblox, especially if your goal is to unlock the Diamond Rod. Many players already meet the quest requirements but still get stuck simply because they cannot find Larry or do not know how to activate the quest. Without interacting with this NPC, Diamond Rod progression cannot even begin.

This guide explains who Larry is, where to find him, the fastest route to his location, and what you need to prepare before starting the Diamond Rod quest. Also check out our Fish It Codes for more rewards!

Who Is Larry in Fish It Roblox?

Larry is known as the Diamond Researcher, the NPC responsible for handling the entire Diamond Rod questline. Every major step, from submitting mutated items to turning in secret fish, is managed through him. Larry’s Main Roles:

• Gives the Diamond Research Quest
• Accepts quest items such as Mutated Gemstones and Lochness Monster
• Tracks your overall Diamond Rod progress

If you cannot find Larry, it usually means you are not in the correct area yet.

Larry Location in Fish It Roblox

Larry is located inside a special area called the Mutation Cellar, which can be accessed from Fisherman Island. How to Reach Larry

1. Travel to Fisherman Island
2. Look for the entrance leading to Mutation Cellar
3. The door is marked with a diamond icon, making it easy to identify
4. Enter the door and teleport into the area
5. Inside the Mutation Cellar, you will find Larry (Diamond Researcher)

Larry does not move or change locations. As long as you are inside the Mutation Cellar, he will always be in the same spot.

How to Start the Diamond Rod Quest

Once you find Larry, activating the quest is straightforward.

• Talk to Larry
• Select Diamond Research Quest
• The quest will instantly appear in your mission list

If the Quest Option Does Not Appear, This usually happens for one of the following reasons:

• You do not own the Element Rod yet
• Your inventory is full
• You have not met the requirements from the latest update

Make sure all basic conditions are met before interacting with Larry again.

How to Submit Quest Items to Larry

Several Diamond Rod missions do not require you to catch items again if you already own them. Items That Can Be Directly Exchanged:

• Mutated Gemstone (such as Ruby Mutated)
• Lochness Monster

Exchange Process

1. Take the required item out of your inventory
2. Talk to Larry again
3. Choose the Exchange Item option
4. Select the requested item

If the item is correct, the quest progress will update immediately.

Larry is the key NPC for unlocking and completing the Diamond Rod quest in Fish It Roblox. Once you know that he is located inside the Mutation Cellar on Fisherman Island, the entire process becomes much clearer.

After activating the quest, your main focus should be finishing each mission and returning to Larry to update your progress. By understanding Larry’s location and function, you can avoid unnecessary confusion and move straight toward earning the Diamond Rod more efficiently.
