The newest update in Fish It introduces a hidden fishing location known as the Sewers. This area was actually sitting in the game long before the update, but players could not access it because the entrance was completely blocked. Now that the path is open, players can explore the dark underground area and try catching several new fish.
The Sewers bring a different atmosphere compared to other fishing spots. The environment looks dirty and radioactive, matching the strange mutated fish that live there. Among the new catches, there is also a secret fish called Bonemaw Tyrant, which has quickly become one of the most interesting targets for collectors.
In this guide, you will learn how to unlock the Sewers, what you can find inside the area, and the best way to try catching the Bonemaw Tyrant. Also check out our Fish It Codes for more rewards!
How to Unlock the Sewers in Fish It
Unlocking the Sewers is actually very simple. You do not need to complete any complicated quests or tasks.
All you need to do is head to the Underwater City. Once you arrive there, look for the cave located right in front of the Duck Boy NPC. Before the recent update, this cave entrance was completely sealed, so most players ignored it.
After the update, the cave is now open. Simply walk through the entrance and it will lead you directly into the Sewers area.
Inside the Sewers, you will find two different fishing spots where you can cast your line. The environment is darker than most locations in the game, with a grungy sewer theme that fits the radioactive creatures living there.
What You Can Find Inside the Sewers
The Sewers introduce five new fish species that players can catch. Some of these fish can also be found in the Underwater City, but a few are unique to this location.
However, the main reason many players visit the Sewers is to hunt for the secret fish hidden in the area.
Before you begin fishing, it is recommended to purchase the Radioactive Charm. This item can be bought directly inside the Sewers.
Radioactive Charm Details
- Price: 20,000 Coins
- Effect: Increases radioactive mutation chance by 1.3x
This charm does not increase the chance of catching specific fish, but it does boost the chance of getting radioactive mutations. For players who enjoy collecting rare fish variants, this item is very useful.
How to Get Bonemaw Tyrant in Fish It
The most valuable catch in the Sewers is the Bonemaw Tyrant, which is the secret fish for this location. Catching it is not guaranteed, so players may need to spend some time fishing before they finally find one.
Bonemaw Tyrant Information
- Fish Type: Secret
- Location: Sewers (Underwater City)
- Max Weight: Around 220 kg
- Average Weight: Around 150 kg
- Theme: Radioactive / Mutated
Compared to other secret fish in Fish It, the Bonemaw Tyrant is slightly smaller in size. Most players will catch one around the 150 kg range, although the maximum weight can reach roughly 220 kg.
Tips to Increase Your Chances
Since Bonemaw Tyrant is a secret fish, there is no guaranteed method to catch it. However, a few strategies can help improve your odds.
1. Equip the Radioactive Charm
Using the Radioactive Charm helps you lean into the mutation theme of the Sewers. While it does not directly boost the spawn rate of Bonemaw Tyrant, it can still increase the chances of radioactive fish appearing.
2. Fish During Bloodmoon Events
One of the earliest recorded Bonemaw Tyrant catches happened during a Bloodmoon event. Because of this, many players believe the event may increase the chances of encountering rare fish.
3. Switch Between Fishing Spots
The Sewers contain two fishing areas. If you are not getting good results in one location, try moving to the other spot and continue fishing there.
The Sewers is one of the more unique fishing areas added to Fish It so far. Its radioactive theme, darker environment, and strange mutated fish make it stand out from other locations in the game. While some of the fish overlap with the Underwater City, the real highlight of this area is the secret Bonemaw Tyrant.
If you are trying to complete your collection or simply enjoy hunting rare fish, the Sewers is definitely worth exploring. Bring enough coins for the Radioactive Charm, watch for Bloodmoon events, and be ready to spend some time fishing until the Bonemaw Tyrant finally appears.
