A giant slug can attack with its bite, but prefers to attack targets with its highly corrosive spittle.
Giant slugs dwell away from light, preferring the depths of dungeons and similar places. Giant slugs are able to eat substances like wood or burrow through very hard earth using their rasp-like tongues.
Giant slugs appear as larger versions of normal slugs. They are about 25 feet long and can grow to be 50 feet in length. Most are pale gray in color with a pale white underbelly.
The Giant Slug first appeared in the Monster Manual (Gary Gygax, 1977).
