To complete the Duomension City Bizarre Melody puzzle, enter an Interplanar Jump, find the terminal in Difficulty III, and play the Grand Carnival score: ↑, ↗, ↙, ↘, →, ↖, ↓, ↖. The melody opens a hidden stage with a chest; a follow-up heart-lever puzzle can also unlock the Arcadia Variation: Rabbit Hill achievement.
Where to find the Duomension City Bizarre Melody terminal
- Start Interplanar Jump: Difficulty III in Duomension City.
- Continue until you reach the office area. Take the portal on the left rather than the route that exits the area; this leads to the Bizarre Melody terminal, according to Nerd’s Chalk’s Duomension City walkthrough.
- Once inside an Interplanar Jump, open the Furbobo head/menu at the upper left to access the Bizarre Melody input interface, as described in Icy Veins’ Planarcadia guide.
Duomension City Grand Carnival score
Enter the directions in this order:
- Up (↑)
- Up-right (↗)
- Down-left (↙)
- Down-right (↘)
- Right (→)
- Up-left (↖)
- Down (↓)
- Up-left (↖)
The full sequence is ↑, ↗, ↙, ↘, →, ↖, ↓, ↖. Icy Veins lists this as the Duomension City Grand Carnival score in a guide updated for Version 4.5 on August 28, 2026. Nerd’s Chalk’s February 16, 2026 walkthrough gives a different sequence for some diagonal inputs, so the two written guides do not independently confirm the complete code. Use the sequence above as the best-supported listed answer, but if it does not work in your current game version, check the displayed directional prompts rather than mixing the two codes.
What to do after entering the melody
The melody takes you to a hidden stage containing a chest. After opening it, look for a platform puzzle with two levers and two circling halves of a heart.
- Watch the moving heart halves and wait for one to pause.
- Pull the lever corresponding to that half to lock it in place.
- Repeat for the other half. Reuniting the heart frees the imagenae and completes the follow-up puzzle, according to Nerd’s Chalk.
Rewards
Nerd’s Chalk reports that the hidden-stage chest contains 5 Stellar Jade plus upgrade materials. Completing the heart puzzle unlocks Arcadia Variation: Rabbit Hill, which that walkthrough reports as worth another 5 Stellar Jade. These quantities are from the walkthrough rather than an official HoYoverse source.
