Guide to call the secret phone number found on the official soundtrack for the game
Source of the number
Scrolling through the bandcamp page of the official soundtrack (located here), I noticed that the track “Mystery” had a number after it in the title, about the length of a phone number in the phone booth.
How to call it
Start up Dragon, swim across the pool, and enter the first door. Go directly to the phone booth and tap in this number:
555 0 555 8959
There should be a secret waiting for you if done correctly (I don’t want to spoil the surprise with how easy it is to do on your own). Enjoy!
