Vanoorian ammonia was a type of ammonia found on Vanooria. During the evacuation of Yavin 4, Rebel pilot Evaan Verlaine nicknamed Princess Leia Organa the "ice princess" and mockingly questioned what kind of Vanoorian ammonia Organa was filled with. Overhearing the statement, Organa said she had never been to Vanooria and corrected Verlaine for her disrespect.
