Crawler is an enemy family in Final Fantasy Dimensions. They look Sarlacc-esque.
Though the Slagworm claims to be a worm, its Japanese name is Slug Crawler (スラッグクロウラ, Suraggu Kuroura?). In Japanese, the other two enemies of the family with "Crawler" in their name spell it with different katakana; (クロウラー (Kurourā?) for Death Crawler and クローラー (Kurōrā?)) for Sand Crawler.
