How to Get Blood Moon Whale in Fish It
The Blood Moon Whale is a secret, event-exclusive fish and is one of the hardest catches in Fish It, with a 1 in 5 million catch rate. To even have a chance at catching it, you must be actively fishing during the Blood Moon Event. Follow the steps mentioned below to catch this fish:
- First, you need to reach Mount Hollow by heading to the ghost ship dock on Fisherman Island.
- Stand on the glowing teleport circle to be transported directly to Mount Hollow.
- Equip your highest-tier fishing rod with Luck enchantments. Also, equip baits and bobbers to boost rare fish catch chances.
- Start fishing as soon as possible. Once the event begins, don’t waste any time. The Blood Moon Whale only spawns within this 5-minute event window.
When you hook the Blood Moon Whale, a dark red animation appears around your fishing line and reel. The reeling minigame is slightly harder than usual, so be prepared to time your pulls carefully.

How to Get Blood Moon Mutation in Fish It
The Blood Moon Mutation is a new, ultra-rare fish mutation added alongside the Blood Moon Whale. This mutation can appear on any fish caught during the Blood Moon event, not just the whale, but also on all other fish. Follow these steps to get this mutation:
- First, participate in the Blood Moon Event. You must be fishing during the active 5-minute window while the Blood Moon sky is visible.
- Use a mutation Bait as it increases your odds of triggering the Blood Moon variant when fishing.
- While the event affects all maps, try fishing in Mount Hollow since it has a higher Blood Moon mutation frequency.
- Once you catch a fish, check for its visuals. Blood Moon Mutated fish have a red glow and may emit faint light trails when caught.
Each Blood Moon Mutation increases the fish’s sell value significantly. It is speculated to be a 10x multiplier in value for Blood Moon Mutated fish.
