Disco Pufferfish Fish It Guide, Location & How to Catch!

The Classic event in Fish It adds a wide range of new fish, and one of the most talked-about additions is the Disco Pufferfish in Fish It. This fish isn’t something you can catch by random luck in normal waters. Instead, it belongs to the mutation category and requires specific conditions to appear. If you’ve been struggling to figure out how to farm it efficiently, this guide explains everything you need to know, step by step. Also check out our Fish It Codes for more rewards!

What Makes the Disco Pufferfish Special?

The Disco Pufferfish is an Epic Mutation fish, and it only exists for the duration of the Classic event. Because it’s both event-limited and tied to a special mechanic, many players hunt it to complete the Classic Island index or fill their event progression rewards. If you’re collecting mutation fish or aiming to finish the pass, this one should be on your priority list.

Where to Catch Disco Pufferfish

This fish does not spawn in normal fishing zones. The only place where you can find it is:

• Iron Cavern (Classic Island)

Make sure you know how to reach this area before attempting to farm.

Requirements Before You Can Catch It

You’ll need to meet a few conditions first:

• Minimum player level: 200
• Must already have access to Iron Cavern
• Only appears while the Disco Event is active

Iron Cavern was introduced with the Classic update and features a neon, hacker-style environment. To unlock it, you must sacrifice the following four fish at the entry podium:

• Builderman Guppy
• Guest Guppy
• Brighteye Guppy
• Shedletsky Guppy

Once placed, the portal unlocks permanently. Keep in mind: if you haven’t reached level 200, you won’t be allowed in the area where this fish spawns.

When Does the Disco Pufferfish Spawn?

The fish will only appear during the Disco Event. Event schedule:

• Occurs every 2 hours
• Lasts for a limited time once activated

During this window, spawn chances increase and the Disco Pufferfish becomes available.

Tips to Improve Catch Rates

Since this fish belongs to the mutation category, the spawn rate isn’t high. These tips can speed up your progress:

• Use a rod with high Luck Higher Luck means more Rare, Epic, and Mutation hooks.
• Use boosts or totems if available Event boosts help shorten grind time.
• Stay inside Iron Cavern for the entire event duration Leaving or changing zones can interrupt chances.
• Keep inventory space open Full slots can cause missed drops.

Can You Farm It AFK?

Technically yes, but manual play gives better timing and positioning — especially since you need to be present when the Disco Event begins. AFK farming works if you’re only grinding for casts, but for the Disco Pufferfish specifically, being active is more efficient.

The Disco Pufferfish isn’t a casual drop — it requires timing, access, and the right setup. As long as you: Unlock and enter Iron Cavern, Reach level 200 and Fish during each Disco Event! You’ll have a solid chance of catching one before the event ends.

Start farming early and stay consistent with the Disco Event cycle. With the right timing and a little patience, you’ll eventually secure the Disco Pufferfish and complete one more milestone in the Classic event.
