Fish It Update Guide Atlantis Machine, Secret Mutant Runic Koi Event, and New Eldritch Spirit Bobber!

The latest Fish It Roblox update adds several new features for players who enjoy spending time fishing across the game’s islands. This update introduces a special machine that can give boosters, a timed fishing event with a secret fish reward, and a new bobber that players can collect.

Some of these additions are only available during certain periods, which means players need to take advantage of them while they are active. If you want to improve your chances of catching rare fish or collect the newest items from this update, understanding how each feature works will help a lot.

Below is a complete guide covering the new Atlantis Machine, the Secret Mutant Runic Koi fishing event, and how to get the Eldritch Spirit bobber. Also check out our Fish It Codes for more rewards!


Atlantis Machine in Underwater City

One of the most interesting additions in this update is the Atlantis Machine, which can be found in the Underwater City area. This machine allows players to exchange fish they have already caught in order to receive random boosters. Instead of letting extra fish sit in your inventory, you can donate them to the machine and gain useful temporary bonuses. The process is simple:

  1. Go to the Atlantis Machine in Underwater City.
  2. Donate the fish you have caught.
  3. The system converts those fish into points.
  4. Points are then exchanged for random booster effects.

Several boosters can appear from the machine, including:

  • Luck Boost – increases the chance of catching rare fish
  • Mutation Boost – improves the chance of catching mutated fish
  • Speed Boost – reduces fishing time
  • Big Catch Boost – increases the chance of catching larger fish
  • Shiny Boost – improves the chance of shiny fish appearing

Each booster comes with a limited duration. Some last 30 minutes, while others can last 1 hour or even 1.5 hours. The more fish you donate, the better your chances of receiving useful boosts.


Secret Mutant Runic Koi Fishing Event

Another major addition in this update is the Secret Mutant Runic Koi fishing event. This event gives players a chance to catch a secret fish known as the Mutant Runic Koi. However, the event does not stay active all the time. It appears only at certain times during the day. In many servers, the event usually appears every four hours. A common example schedule looks like this:

  • 07:00 WIB
  • 11:00 WIB
  • 15:00 WIB
  • 19:00 WIB

During the event period, players can fish in the event area to try their luck.

One interesting mechanic is that the chance of getting the secret fish increases when more players are fishing in the event zone. Because of this, busy servers often give better chances compared to empty ones.

Since Mutant Runic Koi is classified as a secret fish, catching it can be difficult. Using boosters from the Atlantis Machine can help improve your chances.


How to Get the Eldritch Spirit Bobber

This update also adds a new cosmetic item called the Eldritch Spirit Bobber. Players can purchase this item for: 5,000,000 Coins! There are two locations where you can buy this bobber.

1. Fisherman Island

The first location is Fisherman Island. You can teleport to the island and visit the shop that sells bait and bobbers. Inside the shop menu, you will find the Eldritch Spirit listed as a new item that can be purchased directly.

2. Underwater City Shop

The same bobber can also be found in the Underwater City shop. Interestingly, in this shop the item appears under the name Mythical Wooden Bobber, even though it is actually the same Eldritch Spirit bobber.

Keep in mind that this item is only a cosmetic bobber skin. It does not provide extra stats or gameplay buffs. Even so, many players still collect it because of its unique design and appearance.


New Music Settings Feature

In addition to fishing content, the update also introduces a small but useful feature in the settings menu.

Players can now manually disable background audio, including:

  • Music
  • Ambient sounds

To use this feature, simply open the Settings menu and turn off the Music or Ambience options.

This option is helpful for players who prefer a quieter experience or want to focus more while fishing.


The latest Fish It Roblox update adds several features that make fishing more interesting. The Atlantis Machine provides helpful boosters, the Secret Mutant Runic Koi event offers a rare fish challenge, and the Eldritch Spirit bobber gives players another cosmetic item to collect.

Players who want to catch rare fish should take advantage of the Atlantis Machine boosters and participate in the fishing event whenever it appears. Since some of these features are tied to limited events, it is a good idea to focus on fishing during the active periods before the event disappears.
