The Fisch FischFright 3 bestiary is live for Halloween 2026, and it is the biggest version of the event yet. If you have played FischFright before, you know the drill, but this year the pool is larger, the conditions are more varied, and some of the rarest catches like Dobhar and Ghoul Nessie have very specific requirements that are easy to miss. Whether you are a returning player or jumping into FischFright for the first time, this guide covers every fish, what bait to use, what weather to wait for, and which ones you can only get through Trick or Treating or specific pool locations.

How to Reach FischFright 3 Island

To access the FischFright 3 event area head to Moosewood Dock and speak to Captain Jack on the Haunted Ship. Select the “I want to Travel” option and you will be taken to the limited-time Caustic Hallow event island.

Trick or Treating is worth knowing about but it should not be your main strategy for finishing the bestiary. Open your inventory, slot the Candy Bucket into your taskbar, then head to any house on the island and knock. When the NPC answers pick Treat and you might walk away with a fish or just some candy. The keyword there is might since it is not guaranteed and you can go several doors without seeing anything useful. Fish when you can and treat Trick or Treating as a bonus rather than a farming method.
