Go in the Geyser Terrain, solve the puzzle normally, then click the black book. A black key should appear, jump on it. Then go to the Gear Stage and solve the puzzle, then go to the piano and enter "cbdegajfngcdjbfnae" which should spawn a door. Open it with your black key, and you'll be teleported to The Secret Place and start the boss fight. Jessetc has a video on it, skip to 7:04  https://www.youtube.com/watch?v=ScZqlyyu3IA&t=627s
