The Leech display is a display case that can be found in the basement of the Varrock Museum. It depicts a Leech in the Mort Myre Swamp. Players may push the button in front of the case to see the exhibit come to life, or speak to the nearby Natural historian to receive a lecture on the creature's history.
- There is an unused model in the game files showing an oversized and much more vicious leech. It is possible that this monstrosity would have appeared when answering the Natural history quiz questions incorrectly, as a humorous representation of what the Player character thinks a leech looks like.
