Fisch Update Guide: How to Complete the Moby Update and Mariana's Veil Events

Complete Fisch update guide covering Captain Ahab's quest, the Moby fish, Song of the Deep relic, Mariana's Veil bestiaries, rods, and rewards.

Roblox's Fisch keeps dropping content at a rapid pace, and keeping up with every quest, fish, and reward can feel like a full-time job. This Fisch update guide breaks down the two biggest recent content drops — the massive Mariana's Veil expansion and the follow-up Moby Update — so you know exactly what to do, where to go, and what rewards are worth chasing. Whether you're hunting a five-percent-rarity Moby or grinding your way through five layers of deep-sea bestiaries, this walkthrough has you covered.

Let's dive in.

What's New in the Moby Update?

Following the huge Mariana's Veil expansion, the developers shipped a smaller but still rewarding mini-update centered around a giant white whale called Moby. It also opens a new portal to the Calm Zone. Here's a quick overview of everything the update includes:

How to Catch Moby in Fisch

Moby is the star of the new Whale Migration event. It works much like the Orca Migration: when the event kicks off, every player on the server gets an announcement, and a trail of blue arrows appears across the ocean pointing toward the migration zone.

Key details to know before you set sail:

  • Each Whale Migration spawns two Blue Whales per event.
  • Moby only has a 5% chance of appearing in a migration, so expect multiple event runs.
  • Moby is an exotic/secret rarity fish, meaning the catch itself requires patience and a solid rod.

Since the spawn odds are low, don't burn out chasing it in one session. Community reports suggest hopping servers or queuing up other tasks (like bestiary grinding) while waiting for the next migration announcement.

Captain Ahab's Quest and Rewards

Once you've landed a Moby, bring it to Captain Ahab in Moosewood. You'll find him near the Shipwright, standing by the event platform. Hand over the fish and he'll reward you with two items:

RewardDetailsRepeatable?
Song of the DeepEnchant relic for the Keepers AltarYes — quest can be repeated
The Moby BobberWhale-shaped bobber used while castingNo — first completion only

The best part of this Fisch update guide tip: Captain Ahab's quest is repeatable, so if your enchant attempt fails (more on that below), you can grind another Moby and try again with a fresh relic.

Song of the Deep and the Blessed Song Enchantment

The Song of the Deep relic gives you a 20% chance to roll the Blessed Song enchantment when used at the Keepers Altar. Blessed Song boosts your rod's Progress Speed by 30%, which dramatically shortens the reel time on fish that normally take ages to land.

The catch? The enchant can fail — and with an 80% failure rate, it probably will, more than once. That's exactly why the repeatable quest matters. Treat each Moby hunt as a ticket to another enchant roll rather than a one-and-done chore.

Double XP Week

Running alongside the update is a three-day double XP event. Every fish caught grants twice the experience, making it the ideal window to grind levels or knock out tough bestiaries. Pro tip from experienced players: equip any rod with the Hasty enchantment to maximize your catches per hour during the event.

Premium Bundles, Rod Skins, and Bobbers

If you're willing to spend Robux, the update also brought limited-time cosmetics:

Mariana's Veil: The Full Update Breakdown

Before Moby arrived, Fisch launched its biggest expansion to date: Mariana's Veil. Like Atlantis, it's a permanent update, so there's no need to rush through it. Still, the amount of content is staggering — five bestiaries, secret fish, three submarine upgrades, puzzles, a boss fight, and five new rods.

Step 1: Build the Submarine with Dr. Glimmerfin

Head to Roslit Bay's lighthouse area and talk to Dr. Glimmerfin. His quest has you constructing a submarine, which becomes your ride down into Mariana's Veil. This is your entry ticket to everything the update offers, so knock it out first.

Step 2: Explore All Five Layers and Their Bestiaries

Mariana's Veil contains five distinct zones, each with its own bestiary and one secret fish that triggers a cutscene when caught:

LayerFish CountSecret Fish
Volcanic Vents9Magma Leviathan
Challenger's Deep9Frozen Leviathan
Abyssal Zenith9Crowned Anglerfish
Calm Zone8Crystallized Seadragon
Veil of the Forsaken8Scylla

Highlights include the Hellfire Haddock and Pyrite Pufferfish in the Volcanic Vents, the Cryo Coelacanth in Challenger's Deep, and the Kraken Koi waiting in the Veil of the Forsaken.

Step 3: Upgrade Your Submarine and Collect Glimmerfin Suits

You can upgrade the submarine three times, but only within the first three layers. Each upgrade also earns you a new tier of the Glimfin Suit — essential gear, since you must wear the right suit level to survive each zone's temperature.

UpgradeLocationRequired ResourcesReward
1Volcanic VentsLava Crystal, Inferno Hide, Infernal Iguanafish, Blisterback BlennyHeat Upgrade + Glimmerfin Suit Lv. 1
2Challenger's DeepIce Crystal, Cryoskin, Polar Prowler, Glimmerfin Suit Lv. 1Ice Upgrade + Glimmerfin Suit Lv. 2
3Abyssal ZenithAngler's Lantern, Abyssal Bearded Seadevil, Voidglow Ghostfish, Glimmerfin Suit Lv. 2Deep Upgrade + Glimmerfin Suit Lv. 3

Plan your catches around these requirements — fishing for upgrade materials as you go saves a lot of backtracking.

Step 4: Solve the Calm Zone Puzzles

The Calm Zone (fourth layer) holds three puzzles in the spirit of Atlantis' Zeus Trial. Completing them unlocks the final area, the Veil of the Forsaken:

PuzzleSolution
1. ObbyJump across floating rocks and finish the obstacle course.
2. Giant GatePlace the Magma Leviathan, Frozen Leviathan, and Crowned Anglerfish on their podiums.
3. Scylla Boss FightPosition four chess pieces correctly and assemble a crossbow while dodging Scylla's fireballs.

This is why you shouldn't release or sell your secret fish — you'll need three of them to open the Giant Gate.

Step 5: Join Scylla Hunts

After the puzzles, you'll reach a pond where Scylla Hunts occur. It's a server-wide event announced to everyone, but only players with access to the Veil of the Forsaken can actually participate. Catching Scylla itself is the crown jewel of the update's fishing challenges.

Step 6: Grab the Five Exclusive Rods

Mariana's Veil introduced five powerful rods, each leaning toward money, EXP, or both:

  • Volcanic Rod
  • Challenger's Rod
  • Rod of the Zenith
  • Ethereal Prism Rod
  • Leviathan's Fang Rod

Fair warning from the community: most of these carry a hefty price tag, so budget your in-game cash accordingly. Premium bundles and boats are also available — watch for boats docking at various islands to snag limited items.

Which Update Should You Prioritize First?

If you're short on time, here's a suggested order:

  1. Double XP Week (when active) — grind levels while the 2x bonus lasts.
  2. Dr. Glimmerfin's quest — it gates all of Mariana's Veil.
  3. Whale Migration events — start farming Moby attempts early, since the 5% spawn rate means luck is a factor.
  4. Calm Zone puzzles and Scylla — for the endgame rewards and rods.
  5. Captain Ahab's quest repeats — keep rolling Song of the Deep until Blessed Song lands on your favorite rod.

Frequently Asked Questions

How rare is Moby in Fisch?

Moby has roughly a 5% chance of spawning during a Whale Migration event, and it's classified as an exotic/secret rarity fish. Expect multiple migrations before you see one.

Can you repeat Captain Ahab's quest in Fisch?

Yes. You can complete the quest as many times as you like to earn additional Song of the Deep relics, which is essential given the enchantment's high failure rate. The Moby Bobber, however, is a one-time reward from your first completion.

What does the Blessed Song enchantment do?

Blessed Song increases your rod's Progress Speed by 30%, letting you reel in slow, heavy fish much faster. It's applied via the Song of the Deep relic at the Keepers Altar, with only a 20% success chance per attempt.

Is Mariana's Veil a permanent update in Fisch?

Yes — just like Atlantis, Mariana's Veil is permanent content. You can work through its bestiaries, submarine upgrades, and puzzles at your own pace without worrying about a deadline. For the latest official announcements, keep an eye on the official Roblox website.
