A huge halibut is an abnormally large halibut caught while rod fishing or trawling at a halibut, shimmering, or glistening shoal. Upon a successful roll for a catch, players or crewmates have a 1/4,000 chance to obtain one from a halibut shoal, an effective 1/20,000 chance from a shimmering shoal, and an effective 1/5,000 chance from a glistening shoal.
Catching one results in the game message You catch a huge halibut! instead of the usual You catch a halibut!. If a crewmate catches it, the game message will show Jolly Jim catches a huge halibut! for example.
When obtained while trawling, the collection log entry will be completed, even if the player does not collect the huge halibut from their trawling net.
