Stoplight Loosejaw guide

With 8000 base XP, Stoplight Loosejaw sits fourth among the 100 Mythical fish and 221st across all 1,260 fish. Tarnished Moongill pays more at 8500, Diamond Daisy matches it at 8000, and then the Mythical list falls off to Lunar Monkfish (5500) and Terrosunder Skull (5400).

It lives inside the Cultist Lair, in two rooms: the Hall of Whispers and The Sanctum. The conditions are narrow, because Minnow bait, Night, Windy weather and Winter all apply at once, so this is a fish you set up for rather than one that turns up by chance.

The Bestiary quote describes a deep-sea dragonfish with red and green bioluminescent lights that it uses to hunt zooplankton, which explains the traffic-light name. Reeling it in can draw ‘A Stoplight Loosejaw!’, ‘Glowing nightmare!’ or ‘Jaws of doom!’
