The inside of the cavern is a relatively small cave filled with purple fungus. In the middle, a duffle bag can be found between the remains of earlier victims. The cavern's main corridor branches to a north room that is filled with four night stalkers.
The western room contains five night stalkers and a high level loot duffle bag. After three days, if the stalkers are killed, up to 13 other stalkers will respawn (4 x 100% chance, 5 x 75% chance, and 4 x 50% chance, first random encounter). After another four days, if four night stalkers are killed (those having 100% chance of re-spawning), two deathclaws and two young deathclaws will spawn (second and last random encounter).
A suit of reinforced combat armor with a helmet can be found in a duffle bag in the cave's western room.
Walking Box Cavern appears only in Fallout: New Vegas.
