Desolate Maw Demonhold Bizarre Melody Location

To reach the puzzle platform, enter Interplanar Jump! Difficulty III and follow these steps:

• Take the 2 elevators up from the start.
• Use the jumping pad and land on the button to open the door ahead.
• Enter the rocket and press the button inside.
• Exit right, jump to the platform with the red button, and press it to destroy the first set of blocks.
• Move right again, jump to the next platform, and press that button to clear the second set of blocks.
• The lowered platforms now create a path to the Bizarre Melody Platform. Interact with it to begin the puzzle.

Bizarre Melody Puzzle Solution

The puzzle requires you to press the directional buttons in a specific order. If you haven't found the hint yet, here's the direct solution:

• Press the buttons in the order shown in the image below (sequence matching the fireworks pattern). The correct order is Up, Right, Down, Left, Up, Right. (You can verify this by watching the fireworks from a hidden viewpoint, detailed in the next section.)

Once you input the correct sequence, you're teleported to a hidden stage containing the Princess's Moon sphere.

If you want to discover the solution organically:

1. From the rocket location, go left and jump to the left platform.
2. Press the handle to levitate the platform.
3. Run up the curve to flip the screen perspective.
4. Jump to the yellow button and press it to launch fireworks.
5. The fireworks display reveals the order of arrows for the Bizarre Melody puzzle.

How to Free the Princess's Moon

After solving the puzzle, you'll be in the hidden stage. To free the sphere and earn the Arcadia Variation: The Princess's Moon Achievement:

• Jump to the upper platform.
• Activate the lever.
• Double‑jump toward the gravity line to flip orientation.
• Move right and use the jumping pad to flip gravity again.
• Head toward the portal door and interact with it.
