Fisch, one of the most sought-after Roblox fishing adventures, recently unleashed a new update named “Fisch Tidefall”. To liven up your fishing gameplay, it has introduced a variety of fishes – each with unique abilities.
Among a plethora of new add-ons, the one that has been dominating the landscape is “Plesiosaur.” So, what makes it stand out, and whether or not you should also go all in to grab it? To clear the clouds, let’s jump right in to discover the proven ways to catch Plesiosaur in Roblox Fisch and figure out how you can get the most out of it!
What is the Plesiosaur in Fisch?
The Plesiosaur in Fisch is a new exotic fish that was brought to the experience through the Tidefall update. Being exclusive to the Tidefall sublocation, the fish boasts large flippers, which play a pivotal role in helping it swim around the new sublocation in Tidefall.
Where can you find the Plesiosaur?
The fascinating fish can be found in the Tidefall Castle- one of the many sublocations of the Tidefall map. In order to get access to the Tidefall Castle, you’ll need to complete the Oblesik Puzzle. After you complete this quest, you can get access to the new castle.
How to get to the new Tidefall Map?
Keep in mind that you cannot jump in Fisch and reach Tidefall without completing a pacific quest. Here’s what you will need to do.
- Once you spawn into Moosewood Village, head to the Shipwright and spawn your boat. You can use anything that you have unlocked to reach The Underwater.

- While in the boat, grab your GPS and set the coordinates to 3223, 130, 850.
- On reaching the Underwater area, hop into the red boat and interact with the NPC Diver.
- The Diver will give you the Lost Diver quest that you need to complete.
- To complete this quest, ensure that you equip yourself with the Advanced Diving Gear, Super Flippers, and the Tidebreaker.

- With the quest now completed, use the Abyssal Tonic. If you don’t have it, you can spend 500C$ and use it to slow down the effect of pressure.
- Head on until you reach the Tidefall map.
How to Unlock the Tidefall Castle?
Upon entering Tidefall, you’ll have to unlock the Tidefall Castle, as that is where you can hunt for the Plesiosaur. However, you’ll need to complete the Oblesik Puzzle. The puzzle requires you to hunt for fish and place them at specific locations. Once you complete all 5 catches, the Tidefall Castle can now be accessed.
