How to Unlock the Second Sea in FISCH
Step 1: Spawn a Boat and Head to Terapin Island
Spawn a Boat – You’ll need one to reach Terapin Island.
Sail to Terapin Island – This is where the secret boss fight takes place.
Step 2: Find the Secret Boss Location
Go Around the Back of the Island – The entrance is at the back side of Terapin Island.
Look for the Sea Traveler NPC – You’ll see him, but he won’t talk to you yet.
Enter the Tunnel – Right next to the Sea Traveler is a tunnel that teleports you to the boss area.
Step 3: Start the Boss Fight
Walk through the tunnel until you reach the boss arena.
The boss fight queue will start automatically.
You can fight solo or with a team (recommended for an easier battle).
Step 4: Defeating the Boss
The boss is chained and imprisoned, and he will attack in phases.
Use the Keeper’s Torch to attack him.

After reaching half HP, his chains break, and he starts throwing projectiles at you.
Keep attacking with Fireballs and avoid getting hit.
Tip: Fighting in a team makes this battle much faster!
