FischFright 2025 has officially arrived, bringing with it an exciting selection of new rods, boats, and, most importantly, mutations. The limited-time nature of this event makes these mutations incredibly valuable, especially since some are crucial for various quests that reward players with upgraded rods and gear. In this guide, you’ll discover how to obtain the Frightful, Spooky, Haunted, and Eerie mutations in Fisch.
To acquire the FischFright mutations—including Frightful, Spooky, Haunted, and Eerie—players can appraise fish at the Halloween Appraiser or obtain them through limited event relics or special rods.
How to Appraise a Fish for FischFright Mutations in Fisch
The FischFright Appraiser is located at Crook’s Hallow. You can reach this spot by interacting with the Flying Dutchman or the Frightful Mirror. Once you arrive, use your Fisch GPS and follow these coordinates: 43, 141, -11623. The Appraiser NPC is positioned behind the Witch, right next to the merchant.
Once you’re at the FischFright Appraiser NPC, the process mirrors the normal Fisch Appraisal method. Follow these simple steps to appraise a fish and unlock the FischFright mutations:
- Approach the NPC and select “Can you appraise this fish?”
- The NPC will appraise the fish at a random price based on its weight and rarity.
- If you’ve purchased the appraiser’s luck game pass, the amount will decrease.
- After appraisal, look for a small green dot on appraised fishes and items, indicating their new status.
