The Vault of Secrets is a vault in the mind of Riley Andersen that holds things she wants to keep secret.
History[]
When Anxiety took over Headquarters, she had Embarrassment put the old emotions in a jar and sent them to the Vault. There, they met Lance Slashblade, a video game character Riley secretly had a crush on, Bloofy, the host of a cartoon for toddlers that Riley still secretly liked, and the Deep Dark Secret. The Deep Dark Secret shattered the jar, freeing the emotions. Then Bloofy called Pouchy, who gave them the dynamite they needed to get out of the vault. The Deep Dark Secret decided not to leave, saying it wasn't time yet. Then Lance Slashblade helped distract the mind worker guards, but accidentally caused them to get locked in the vault themselves.
Joy later returned to the vault to release the Deep Dark Secret. He admitted that the secret was that Riley burned a hole in the rug, while Joy thought it was her peeing in the pool. Upon hearing that, the Deep Dark Secret slunk back into the vault and closed the door.
