As the Cthulu update has finally settled down, you can now focus on completing the new bestiaries in Fisch. If you have completed every bestiary in the First Sea already, eight new locations are awaiting you in the Second Sea. Azure Lagoon is one of those newly added islands with several exclusive fish. It is a cluster of islands with moderate greenery and a big lighthouse where you can enjoy the view.
Don't get too distracted, as certain fish in Azure Lagoon are tough to catch and can slow you down while completing the bestiary. To help with that, this guide highlights the perfect weather, timing, season, and bait to easily catch every fish.
How to catch all Azure Lagoon fish in Fisch (100% bestiary)

As mentioned, the Azure Lagoon is an island in the Second Sea in this Roblox title. To reach it, you must find and interact with the Sea Traveler NPC. You can find him on the western side of Terrapin, standing near the seashore. Once you have talked to the Sea Traveler, get past the wall behind him to enter the Crypt of the Green One.
In this area, you will find a passageway blocked by a big iron gate. To unlock this gate, speak to the NPC standing in front of it. However, it should be noted that you can go to the other side of the passage only if you are on level 200 or above. Failing to meet this requirement will turn you into ashes, as the NPCs there will throw fireballs at you.

At the end of this passage is a boss chamber where the Cthulu boss spawns. To punch your ticket to the Second Sea, you must defeat the Cthulu boss using a Keeper's Torch. Once you defeat this boss, the Second Sea will permanently be yours. Waveborne is the starter island where you will spawn after entering the Second Sea. Consider it like Moosewood of this area.
