How to Get Aquatic Brainrots in Steal a Brainrot
Here are the methods to get aquatic brainrots in the game:
Method 1: Fishing Mini-Game
The main way to collect aquatic brainrots is through the new fishing mechanic. Fishing events happen every hour in Steal a Brainrot, and this is your chance to catch these special water-themed brainrots.
When the fishing event starts, the entire lobby changes into an underwater zone. You’ll see a fishing rod icon appear in the bottom right corner of your screen. This tells you the event is active, and you can start fishing. You will start the game with a basic Starter Rod, but upgrading to better rods from the Fisherman NPC makes a huge difference in what you catch.
Here is how to fish in Steal a Brainrot:
- Equip your fishing rod from the hotbar.
- Hold left-click to fill the power meter.
- Release the button when the bar is near the top.
- Wait for a brainrot to bite. When it does, start clicking fast to reel it in.
- Keep the progress bar from dropping to zero, or the catch will escape.
Method 2: Stealing
While fishing is the main method, you can also steal aquatic brainrots from other players. If someone has already caught a brainrot you need and placed it in their base, you can try to steal it just like any other brainrot in the game.
Go play the game and collect all aquatic brainrots in Steal a Brainrot through the new fishing mechanic and you unlock the Aquatic Base as your prize.
