A popular Ferengi soft drink made with live algae and sold as the slimiest cola in the galaxy, produced by a company chaired by Nilva.
Slug-o-Cola is one of the best-selling drinks in the Ferengi Alliance. It is green, thick with algae and marketed proudly on its sliminess, a selling point that says a good deal about Ferengi tastes.
The drink matters in the Deep Space Nine episode Profit and Lace. Grand Nagus Zek has been deposed for allowing females to wear clothes and earn profit, and the swing vote among the commerce authority belongs to Nilva, chairman of the Slug-o-Cola company. Zek's allies plan to show him that a female can be a shrewd adviser, but Ishka falls ill.
Quark is surgically disguised as a female named Lumba and wins Nilva over by suggesting a new slogan and pointing out that women with money would double his market. Nilva backs Zek, and Brunt's bid for power fails.
