Rock Salt Cartridges

The Doctor arms Tyler and Leela with two canister-like cartridges containing rock salt, their only remaining weapons against the encroaching Fendahleen. Each cartridge appears as a small, metallic cylinder with a trigger mechanism, designed to release a forceful burst of granular salt. Their desperate use reflects the Doctor's urgency—every cartridge counts as the team prepares to defend the lab against the alien entities.
