I’ve spent countless hours diving into the depths of Fisch’s Tidefall update, and let me tell you – hunting for Plesiosaur and Pliosaur has been one of the most challenging yet rewarding experiences I’ve had in this Roblox fishing adventure. These Exotic fish aren’t just rare catches; they’re game-changers that can completely transform your fishing journey.
When the Tidefall update dropped on January 17, 2026, I was immediately drawn to these prehistoric giants. After dozens of failed attempts and way too many hours of trial and error, I’ve finally cracked the code. Today, I’m sharing everything I’ve learned so you can avoid the mistakes I made and catch these legendary creatures much faster.
The Tidefall update is Fisch’s most ambitious content drop yet, introducing an massive underwater cave system with six distinct sublocations. This isn’t just another fishing spot – it’s a completely new world beneath the ocean’s surface, complete with its own ecosystem, NPCs, quests, and of course, some of the rarest fish in the game.
What makes Tidefall special is its hunt event system. Unlike regular fishing where you can catch fish anytime, these Exotic creatures only appear during specific server events. This creates an exciting, dynamic gameplay experience where you’re always on alert for the next hunt notification.
The update also introduced the Obelisk puzzle system, which I’ll get into later, and a whole new tier of fishing equipment designed specifically for handling these powerful creatures. Trust me, you’ll need every advantage you can get.
There’s something incredibly thrilling about the hunt events in Tidefall. I’ll never forget the first time I saw that notification pop up: “A Plesiosaur prowls Tidefall…” My heart started racing, and I immediately dropped everything I was doing to rush to the location.
What I love most about these hunts is the community aspect. When a hunt event starts, you’ll see players from all over the server converging on the same location. There’s this shared excitement and urgency that you just don’t get from regular fishing. Plus, the satisfaction of finally reeling in one of these beasts after hours of trying is absolutely unmatched.
The economic benefits are pretty sweet too. These Exotic fish sell for massive amounts, and more importantly, they’re essential for crafting some of the best rods in the game. The Plesiosaur, for instance, is a key ingredient for the Requiem rod – one of the most powerful fishing rods in Fisch.
Let’s start with the Pliosaur, since it’s slightly more accessible than the Plesiosaur. Here’s everything you need to know:
First, you need to reach Tidefall itself. Head to coordinates 3223, 130, 850 using your GPS. You’ll need a Water Bubble and Tidebreaker to enter the underwater cave system. Once inside Tidefall, head left from the merchant and make your way to 3155, -1052, 1261 (or 3149, -1052, 1297 – both work depending on your approach).
This will take you to the Collapsed Ruins area, where the Pliosaur hunt events occur. Look for the distinctive ruined architecture and underwater entrance – you can’t miss it.
Here’s the crucial part: the Pliosaur only spawns during its dedicated hunt event, which has a 1% chance of triggering during the day. That’s right – just a 1% chance! When it happens, you’ll see the notification “A Pliosaur stalks the Collapsed Ruins…” at the top of your screen.
There’s also a much rarer Ancestral Pliosaur variant that has a 0.005% spawn chance, replacing the regular Pliosaur hunt. This Divine Secret fish is incredibly rare but absolutely worth the effort if you manage to catch it.
Based on my experience, here are the perfect conditions for catching a Pliosaur:
The Pliosaur applies a brutal -90% progress speed effect on your rod. I learned this the hard way when my first catch escaped after I thought I had it secured. To counter this, I recommend enchanting your rod with:
Also, don’t be afraid to server hop. If you’ve been waiting hours for a hunt event with no luck, try switching servers. The events are server-specific, so a fresh server might have better timing.
The Plesiosaur is even more challenging to obtain, primarily because it requires completing the Obelisk puzzle first. But don’t worry – I’ll walk you through the entire process.
Before you can even attempt to catch a Plesiosaur, you need to unlock Tidefall Castle by completing five Runic Obelisk puzzles. Each obelisk requires a specific fish:
| Obelisk Color | Location | Required Fish | How to Get It |
|---|---|---|---|
| Gold | Collapsed Ruins | Goldwraith | Hunt event in Crowned Ruins (0.5% spawn rate) |
| Sky Blue | Near bridge, opposite shop | Reef Titan | Hunt event in Coral Bastion (1% spawn rate) |
| Red | Behind Tidefall shop | Pliosaur | Hunt event in Collapsed Ruins (1% spawn rate) |
| White | Near waterfall | Sparkling Dripstone | Trash item in Tidefall bestiary |
| Purple | Northeast of shop | Omnithal | Hunt event in Sunken Reliquary (1% spawn rate) |
This puzzle took me days to complete, but the feeling of finally unlocking Tidefall Castle was incredible. My advice: tackle the easier requirements first (like the Sparkling Dripstone) and work your way up to the hunt event fish.
Once you’ve completed all five obelisks, head toward the lush green area and glide over the water. You’ll find Tidefall Castle – a massive, imposing structure that serves as the exclusive home of the Plesiosaur.
Like the Pliosaur, the Plesiosaur only appears during its hunt event, which has a 0.25% spawn chance during the day. That’s even rarer than the Pliosaur! The notification will read “A Plesiosaur prowls Tidefall…”
There’s also the Forbidden Plesiosaur variant with a 0.02% spawn chance – this Divine Secret fish appears as a black exclamation mark when you’re about to catch it. I’ve only seen it once, and unfortunately, I wasn’t quick enough to reel it in.
For the Plesiosaur, I recommend:
The conditions are similar to the Pliosaur, but the Plesiosaur seems to be even more sensitive to weather and timing. I’ve had the best success during foggy winter nights – the combination just seems to make these creatures more active.
While you’re working on catching these Exotic fish, don’t forget to grab some free codes! Here are the current active codes for March 2026:
The Tidefall update (version 1.67.0) brought significant changes to the Fisch ecosystem. The most recent patch (1.67.2) improved visibility in certain Tidefall locations during night time, which has made hunting much easier.
What I’m really excited about are the rumored upcoming features:
The developers have been actively listening to community feedback, so I expect we’ll see quality-of-life improvements for the hunt event system soon.
After spending so much time in Tidefall, I’ve picked up some advanced strategies that most guides don’t cover:
Don’t just wait for hunt events – actively seek them out. I recommend:
Both Plesiosaur and Pliosaur are valuable, but don’t just sell them immediately. Consider:
I made plenty of mistakes learning this system. Here’s what to watch out for:
Be strategic about when you play. I’ve found that:
A: Hunt events typically last 10-15 minutes, but they end immediately if someone catches the target fish. That’s why you need to act fast!
A: No, each hunt event ends after one successful catch, regardless of rarity.
A: No, once you complete it, Tidefall Castle remains permanently unlocked for your account.
A: The variants are much rarer (Divine Secret rarity vs Exotic) and sell for significantly more. They also have unique appearances and are highly sought after for trading.
A: Technically possible, but I wouldn’t recommend it. The -90% progress speed debuff makes it nearly impossible without high-tier rods and proper enchantments.
A: Yes, but they’re less effective than in surface locations. Still worth using for the slight advantage they provide.
Hunting for Plesiosaur and Pliosaur in Fisch’s Tidefall update has been one of the most rewarding gaming experiences I’ve had in a while. It’s challenging, sure, but that’s what makes it so satisfying when you finally reel in one of these prehistoric beasts.
The key is patience and preparation. Don’t rush in unprepared – take the time to get the right equipment, understand the spawn mechanics, and optimize your conditions. And most importantly, don’t get discouraged by failed attempts. Even with perfect conditions, these fish are designed to be rare and challenging.
I hope this guide helps you on your hunting journey. There’s nothing quite like the thrill of seeing that hunt notification pop up and knowing you have the skills and equipment to succeed. Happy hunting, and may your reels be ever in your favor!
