The Fishing Event happens every 30 minutes on all Steal a Brainrot servers. It occurs alongside the Radioactive event, causing the entire map to be flooded with neon green waters. An event-exclusive shop also spawns on the map from which you can buy fishing rods.

To begin fishing, equip the fishing rod and cast the line into the water. It is possible to reel in Brainrots while you're inside your base. Once a character is hooked, click on the screen repeatedly to fill the bar, following which your avatar will pull the aquatic Brainrot.

Fishing is only possible if you have empty slots in your base. If you don't have the required space, an error message will appear in red on the screen.
