The River troll was a random event that occurred while a player was fishing. These monsters appeared and attacked players when players made an attempt to fish. They said, "Fishies be mine, leave dem fishies!", before attacking the player. The river troll's combat level varied depending on that of the player's, a minimum of 14, and up to a maximum of level 159. Like most other random events, the River troll could be fled from, as it only had a melee attack.
As with all other aggressive random events, this was removed in an update.
Although being removed from random events, they will spawn when attempting to fish in the Enchanted Valley. If Swan Song has been completed, the troll will burst out of the water saying that the player killed the Sea Troll Queen before attacking.
