Secrets of The World is a bonus level in Pizza Tower, located in the Sound Test room.

The level is a gauntlet, where the player must complete all of the secret rooms from other levels back-to-back in a randomized order, with total of 57 of them. The game chooses a random order for these secrets. Being one of the three stages to lack Pillar John (the others being WAR and Tricky Treat), the player is given a unique timer of 25 seconds per room to complete it. The timer restarts after completion.
