The Haunted Castle went quiet the moment the moon crested the ridge. I felt the Gravestone’s candles snap to life and knew the window had opened — or closed, if you missed it. You can lose hours waiting for the full moon, so timing is everything.
I’ve crafted the Skull Guitar more than once, and I’ll walk you through the exact checks, the puzzles, and the pinch points other guides skip. Follow this and you’ll stop guessing and start finishing. The castle was a wound in the map.
Requirements to Obtain Skull Guitar in Blox Fruits
On many servers you’ll see groups camping the Third Sea at night; the full moon is their calendar. You need to meet a short list of conditions before the puzzle will accept you.
- Player level: at least 2,300.
- Access to the Third Sea.
- A Full Moon event active (appears roughly every 180 minutes).
- Completion of the Haunted Castle puzzle sequence.
- Materials gathered to craft the Skull Guitar.
Want a quick eligibility check? Visit the Gravestone at Haunted Castle — if the candles are lit around it you can start the puzzle immediately.
What level do you need to get Skull Guitar?
You need to be at least level 2,300 to begin the Skull Guitar puzzle at the Haunted Castle.

The castle’s stone steps still smell of rain and torch smoke when the event begins. The whole sequence is six tight steps; miss one and you’ll be sent back outside to wait another 180 minutes.
Pray at the Gravestone
Go to the Gravestone at Haunted Castle during a Full Moon and interact to pray. Full moons announce themselves with the message: “The light of a full moon peaks through the clouds.”
Defeat Six Living Zombies
For the next step you must kill six Living Zombies with a single hit. These are the same enemies that drop the Nightmare Catcher. Kite them into a tight cluster and finish them with an AoE burst (Buddha, Magma, or another high-burst fruit).
Solve the Graveyard Sign Puzzle
Return to the graveyard where two rows of signs stand guard. Interact with signs to turn them white. Count graves on each side; toggle the sign on the side with the most graves. If done right your screen will go black and show “Excellent!”
Talk to the Ghost NPC
Enter the main castle and go to the room right of the stairs. Talk to the NPC named Ghost. The screen will black out again and cue the next puzzle.
Solve the Trophy Puzzle
The garden between the main castle and the Soul Reaper spawn is a brief orientation test. From inside the garden, face the castle and memorize the direction of each trophy handle; screenshot this from above—your life will be easier.
Then head to the electrical room under Haunted Castle and enter the circuit board. Use this rule:
- Handle pointing left–right = make the corresponding line horizontal.
- Handle pointing front–back = make the line vertical.
- Trophies that are trees = leave the tile blank.
Note: trophy positions are randomized per player, so use your own screenshot to avoid mistakes.
Solve the Tile Puzzle
Finally, inspect the floor tiles in the plumbing room. Match tile colors to the blue and red markers on walls and ceiling. If a tile has no colored pipe nearby, leave it alone. Finish correctly and you’ll see “Congratulations” — the Weird Machine is now accessible.
How to Craft Skull Guitar in Blox Fruits
The Weird Machine is tucked inside the castle and it hums with focus. Here are the materials and how to hand them over to claim your Skull Guitar.
| Material | Quantity |
|---|---|
| Bones | 500 |
| Ectoplasm | 250 |
| Dark Fragment | 1 |
| Fragments | 5,000 |
Collect those parts, interact with the Weird Machine, and the Skull Guitar is yours. You can upgrade it: add 1 Dark Fragment, 15 Dragon Scales, and 10 Magma Ore to raise the Skull Guitar damage by +6%.
If you want real-time help, check the Blox Fruits Discord communities or search YouTube creators who post timestamped Haunted Castle runs — those guides often show trophy layouts and tile patterns that save you minutes. Roblox’s own forums and speedrunning threads on Reddit are good places to verify timing windows too.
How many materials do you need to craft the Skull Guitar?
You need 500 Bones, 250 Ectoplasm, 1 Dark Fragment, and 5,000 Fragments to craft the Skull Guitar.
If you plan a run, arrive with a screenshot of the trophies, a burst-damage fruit for the zombie step, and your materials banked. The Weird Machine is a cathedral of gears.
So — are you taking the Skull Guitar to the arena or using it to farm?
