An extremly awful-tasting knock-off of the popular drink Mountain Dew. Made by Coke (see evil), Vault is what vampires drink when they can't find any human blood. Vault is commonly confused with toxic waste, and can be found in septic tanks nationwide.

Vault Girl is the female counterpart of Vault Boy, the Vault-Tec mascot. Unlike the Vault Boy, she only appears for female only perks or accompanies him in various images. The Vault Girl appears rarely contrary to the Vault Boy and only for some representation of perks, reputations, traits and equipment. She also appears in a TV for educating cyberdogs in Big MT. Playing as a female character will not cause the Vault Girl to appear, but downloading mods can help.
