The seasinger can occasionally appear at the Deep Sea Fishing hub. Similar to the historical random events, the seasinger will only focus on a certain player. The player can choose to listen to her voice by left-clicking her, yielding the message: You listen to the seasinger's song.. This will grant the player with Fishing experience (up to 1,940 at level 99 Fishing), yielding the message: You are rewarded for listening to the seasinger - You receive <number> Fishing XP.. The experience is only granted after the seasinger leaves the hub, not at the moment the player clicks on the seasinger.
The Seasinger may spawn in not directly next to the player, requiring them to pay attention to their surroundings. Once spawned, the player has a small amount of time to interact with her, and will de-spawn if not interacted with fast enough. Her dialogue does not appear within the chat window, and only floats above her head.
She sings songs about Gregg 'Groggy' Herring, and the Deep Sea Fishing sea monster and whirlpool random events.
