Corrosive Slug Slime

A thick secretion coats the passageway floor, left behind by giant slug-like creatures. The slime hardens almost instantly upon contact with air, transforming from a viscous liquid to a concrete-like substance that entraps Lang’s foot. The Doctor notes its rapid hardening exceeds that of construction cement, while Peri shifts from initial curiosity to alarm as the danger becomes apparent. The substance clings to surfaces with stubborn persistence, resisting easy removal.
