River-tolls

River-tolls were a type of toll collected by either the Wood-elves or the Lake-men. These river-tolls were occasionally a source of contention between these two group as they had squabbles over whether they could collect or had to pay these river-tolls for passing down the Forest River.The Hobbit, Ch. X: "A Warm Welcome", pg. 194
==In adaptations==
As a result of the similarities between the words river-toll and river-trolls, some readers mistakenly read the word "river-tolls" as "river-trolls", thereby imagining an entirely new creature which Tolkien never intended to exist. As such, these types of trolls never actually appear in J.R.R Tolkien's writings. As a consequence, many adaptations have included river-trolls as being actual creatures that existed within Middle-earth.
In the video game LEGO The Hobbit: The Video Game, River-trolls are actually added as part of a DLC as playable characters, thus making it possible that the game designers were either among those who fell for this common misreading or poking fun at this misreading.
River-trolls can be found in some fantasy games, Beasts of War and RuneScape, for instance.
