Steal A Fish world eater is a high-tier Deep rarity creature introduced in the 3.0 update of the Roblox tycoon game developed by MY FISH FRIEND. It costs $10 trillion in-game cash or 3,000 Robux to buy directly from the river track, generating a massive baseline income of $1.5 billion per second ($1.5B/s).

Because percentage-based secret and limited fish calculate their yields directly from your highest earner, getting a World Eater significantly accelerates your cash generation and serves as a mandatory sacrifice requirement for Rebirth 10.

World Eater Overview and Core Stats

How to Get the World Eater in Steal a Fish

There are three primary methods to obtain a World Eater during gameplay:

  1. Watch the River Conveyor Belt: The unit spawns naturally along the river track outside player bases. Because Deep fish possess exceptionally low spawn odds, players typically monitor the on-screen countdown timer for the guaranteed Deep spawn, which triggers on a regular cycle (approximately once every hour). Server luck boosts purchased with Robux can also increase the frequency of rare spawns along the conveyor.
  2. Instant Purchase via Robux: When a World Eater appears on the river conveyor or prompts during limited rolls, players who lack the $10 trillion in-game balance can choose to purchase it instantly for 3,000 Robux.
  3. Infiltrate and Steal from Other Bases: In public servers, players can raid neighboring bases. If an opponent has a standard World Eater placed on their floor without an active base lock or force field, you can enter, pick up the unit, and carry it back to your base. Defending weapons like the freeze gun, taser, blunderbuss, or slap tools are commonly used to disable defenders during a heist.

Mutation Variants and Income Scaling

While the standard World Eater yields $1.5 billion per second, variants observed in player testing modify its production and security:

  • Void World Eater: A Void mutation doubles its production rate, producing $3 billion per second ($3B/s).
  • Gold Mutation: Visual variant that retains immense collectible value, though standard purchase prices on track spawns remain around $10 trillion.
  • Unstealable Mutation: Prevents opponents from carrying the unit out of your base, eliminating the need to guard it constantly.

Synergy with Scaler Fish

The World Eater's high flat payout makes it an anchor for scaling units. Several Secret, Admin, and Limited units do not produce a static rate; instead, they generate a set percentage based on your single highest-earning fish:

  • Secret Spiderfish: Generates 75% of your best fish.
  • Secret Nightmare Blobfish: Generates 90% of your best fish.
  • Secret Hungry Tung: Generates 120% of your best fish.
  • Secret Hungry Deer / Limited Evil Bloop: Generates 150% of your best fish.
  • Secret The Moon: Generates 160% of your best fish.

Once a World Eater ($1.5B/s) is added to your floor, a unit like the Hungry Tung automatically jumps to $1.8 billion per second, while a 150% scaler jumps to $2.25 billion per second. If you own a Void World Eater ($3B/s), those same scalers leap to $3.6 billion and $4.5 billion per second respectively.

Rebirth 10 Requirements and Warning

Progression past Rebirth 9 requires collecting specific high-tier endgame units. According to recorded gameplay of Rebirth 10, the required turn-ins include:

  • 1x World Eater
  • 1x Mouth Titan
  • 3x Bloop Voids

When submitting a rebirth, the system consumes the required units from your base and inventory. If you possess multiple World Eaters—such as a standard version and a high-earning Void variant—the game may automatically consume your highest-value variant if it is placed in the active base. To avoid losing a Void World Eater, players store prized units on alternate accounts or ensure lower-value duplicates fill the requirement criteria before confirming the rebirth.
