Mature Grotworms are monsters that can be found on the lowest level of the Grotworm Lair. They are frequently killed by players seeking to complete tasks for Slayer or simply as a means of making money. Completion of the Song from the Depths quest is needed to access the Grotworm Lair.

Players with at least level 50 in the Agility skill may use a slide shortcut near the entrance to the Lair as a quick means of accessing the lower levels.
