Lurky Boi are a common ocean enemy in-game they have 150 health and can be killed with any weapon. They are a good source of fish. If attacking make sure to use a raft so they cannot attack because they take 25 health of they bite you. They where likely added as a meaning for people to actually use rafts. They appear as just a fin in the water. Can be turned into a Domestic boi by placing a saddle on it.
