The Vault contains a text field and an angry padlock button below it, referred to as the Guard, although its true name is Spooky. Pressing the button will return a response based on what has been entered into the text field. By entering specific phrases, Icon Kit rewards, secret coins and associated achievements can be unlocked.
Rewards
Enter the codes stated as captions to unlock the respective rewards.
The song that plays in the Vault is Random Song 01 and was composed by Robert Topala under his Newgrounds alias RobTop. It is also used in the Treasure Room.
The face on the padlock resembles the Demon difficulty icon but differs in being grey, having red eyes and lacking horns. Its name, 'Spooky', is mentioned by a loading screen phrase as well as implied by certain Vault responses.
The 'blockbite' code can be found under the Help section of the Settings menu. Upon waiting a few seconds, the phrase will slowly appear in the lower right corner of the screen. After entering it into the Vault, it will not appear again.

Pressing the button without having entered anything will cycle through ordered responses and will repeat upon reaching the end.
