Cave Bugs can be found in the Realm of Memories during the 25th Anniversary event. They had this appearance during RuneScape 2 until a graphical update on 20 March 2007. Like regular cave bugs, they have much faster Hitpoint regeneration compared to other monsters.

A non-attackable version with the same appearance can be found walking clockwise around the south-eastern enclosure, flickering in and out of existence as it walks.
