Locating the Bizarre Melody Puzzle

To arrive at the puzzle’s designated area within Interplanar Jump! Difficulty III, follow this path:

Ascend using the two elevators located at the start.
Utilize the jump pad to reach the pressure plate, which will unlock the gate ahead.
Board the rocket and trigger the internal switch.
Exit to the right, leap to the platform housing the red switch, and activate it to clear the initial blockades.
Proceed further right, jump to the subsequent platform, and toggle that switch to remove the second set of barriers.
These adjusted platforms form a clear bridge to the Bizarre Melody Platform, where you can initiate the puzzle.

Solving the Bizarre Melody Puzzle

Success requires inputting directional commands in a precise order. If you haven’t managed to track down the in-game clue, the required sequence is as follows:

Execute the directional inputs corresponding to the firework patterns: Up, Right, Down, Left, Up, Right. Once finished, you will be transported to a concealed zone holding the Princess’s Moon sphere.

Discovering the Clue

To experience the challenge as intended, you can find the hint by doing the following:

Starting from the rocket, head left and leap to the left-hand platform.
Engage the lever to make the platform levitate.
Traverse the curved path to shift the camera’s perspective.
Locate and press the yellow button to ignite the fireworks, which visually display the correct arrow sequence for the main puzzle.

Liberating the Princess’s Moon

After navigating to the hidden stage, perform these steps to release the sphere and secure the Arcadia Variation: The Princess’s Moon Achievement:

Jump onto the higher platform.
Engage the lever.
Execute a double-jump into the gravity stream to invert your perspective.
Travel right and use the launch pad to shift gravity again.
Advance toward the portal and interact with it.
Lastly, trigger the lever inside to set the sphere free.
