The St.Patrick's Day Update for 2026 introduces a wide variety of things in Fisch, including a limited-time Shamrock Seas Bestiary, a moving Shamrock Express with leprechauns, Rainbow Events, and a Lucky Appraiser. Here is a detailed guide to everything in the update.
Complete Shamrock Seas Bestiary

The biggest highlight of the St.Patrick's Day Update is the Shamrock Seas Bestiary. This new limited-time beastiary features 11 new fish, each with its own set of bait, weather, time, and season requirements. Since this is a lengthy and separate topic, I recommend reading our dedicated Shamrock Seas Bestiary guide to learn about fish locations and the details for catching them.
When does the Rainbow Event spawn in Fisch?

The Rainbow Event Spawns every 45 minutes in the game. When it appears, you will receive a server-wide notification and the Event section tab saying "The Lucky Rainbow has appeared near the X island."Hop on your boat and go straight to the X island to find a large Rainbow near its vicinity.
How to find the Golden Pot O' Gold in Fisch?

The Golden Pot O' Gold is found on a small, tiny piece of an island that spawns next to the Rainbow. Interact with it to get some free money and potions. Remember, you can use the Golden Pot a total of 4 times before it runs out. So, stay alert and travel to the island before others to make use of it.
How to find Clovers in Fisch?

Clovers spawn randomly all across the Fisch universe. You can go near it and pluck it to add it to your inventory. Consuming them will increase your current Server Luck by x2, and eating rare ones will further scale it.
What is the Shamrock Express in Fisch?
The Shamrock Express is a moving ship in Fisch introduced during the St. Patrick's Update. Hop on your boat and look for the green Shamrock Express marker on the screen to locate the ship moving on the open ocean. I recommend using the Gravity Coil or Glider from your boat to reach the moving ship, as the ship's ladder is a bit tricky to hold onto.

After arriving on the ship, you will find multiple Leprechauns, including the captain of the Shamrock Express, who will give you a wide variety of quests. Finishing these will reward you with money, XP, potions, and the Clover Cluster bait that is quite helpful in finishing the Shamrock Seas Bestiary.
Where is the Lucky Appraiser in Fisch?
The Lucky Appraiser is part of the St.Patrick's Day Event Update. However, there is no sign of the NPC either at Moosewood or on the Shamrock Express. We will update the article if we know the exact locations of the Lucky Appraiser.
