The Skull Guitar is a Mythical gun in Blox Fruits, a Roblox game made by Gamer Robot Inc. To get it, you need to reach level 2,300, finish a six-stage puzzle at Haunted Castle in the Third Sea, and craft the gun at the Weird Machine that the puzzle unlocks. The puzzle can only start at night during a Full Moon, so plan your trip around the moon.
| Stage | Where | What you do |
|---|---|---|
| 1. Pray | Gravestone in the graveyard | Pray during a Full Moon at night |
| 2. Living Zombies | Haunted Castle | Defeat six Living Zombies with the same attack |
| 3. Signs | Graveyard | Select the side with more graves in each sign row |
| 4. Ghost | Main castle, room on the right of the stairs | Talk to the Ghost NPC |
| 5. Trophies | Garden, then the electrical room | Enter the trophy code on the circuit board |
| 6. Tiles | Electrical room | Match the floor tiles to the colored pipes |
Requirements for the Blox Fruits Skull Guitar Puzzle
You need three things before the puzzle will start: a character at level 2,300 or higher, access to the Third Sea, and a Full Moon. Haunted Castle is an island in the Third Sea, and the Gravestone sits in its graveyard. Before you pray, walk up to the Gravestone and look for candles. If they are lit around it, you are eligible to attempt the puzzle.
You don't need the crafting materials to start, because they are only used at the Weird Machine at the end. You can work through the puzzle first and collect what you need along the way.
Pray at the Gravestone During a Full Moon to Start the Puzzle
Praying at the Gravestone is what starts the puzzle, and it only works at night while a Full Moon is up. The game tells you the moon has arrived with a chat message: "The light of a full moon peaks through the clouds." When you see it, head to the Gravestone and pray.
After you pray, the screen goes black for a moment, the candles light up, and the puzzle begins. Since the start depends on the moon, the timing is the part you need to plan around. Once the puzzle has started, your progress carries over whether it is night or day, with or without a Full Moon, and even if you switch servers.
Defeat Six Living Zombies With One Attack
The second stage asks you to defeat six Living Zombies at the same time, using the same attack. The puzzle counts a group defeat, not six separate kills, so the work is in the setup. Gather the zombies into one spot first, then use a move that hits all of them at once.
Buddha, Light, and Magma are good options for this step. The goal is to finish all six in a single strike, so pick a move with enough damage to take them down together.
Solve the Graveyard Sign Puzzle by Counting Graves
Return to the graveyard, where two rows of wooden signs sit along the path. Each row has graves on its left and right side. Count the graves on each side of a row, including the cross-shaped ones, and don't count the soil. Then click the sign on the side with more graves, and it will turn white.
Each sign is a choice about which side has more graves, so the count is what moves the puzzle forward. Repeat the process for each row. When you choose correctly, the screen goes black and a message reads "Excellent!"
Talk to the Ghost NPC in Haunted Castle
Head into the main castle and go to the room on the right side of the stairs. The Ghost NPC is inside. Talk to the Ghost, and the screen will go black again.
This is a short stop, but it is the handoff point between the graveyard and the trophy puzzle. Once you've spoken with the Ghost, the next stage opens.
Record the Trophy Layout, Then Enter the Code
This stage has the most moving parts. The trophy layout is random, so the arrangement you see may not match anyone else's, and example layouts may differ from yours. Take your time and record your own.
- Go to the garden between the main castle and the room where the Soul Reaper spawns. Look toward the castle and note the direction of each trophy. A screenshot taken from above makes the handles easier to read.
- Go to the electrical room underneath Haunted Castle, then turn left to find the circuit board.
- Enter the code based on your trophy directions:
- A trophy handle that goes left to right becomes a horizontal line.
- A handle that goes back and forth becomes a vertical line.
- Trees stay blank.
The circuit board is a translation of what you saw in the garden. Each handle becomes a line, and the trees are left blank.
Match the Floor Tiles to the Colored Pipes
The final puzzle is also in the electrical room. Look at the floor tiles in the middle of the room, then compare each one to the colored pipes on the walls and ceiling. Click a tile to change its color until it matches the pipe it lines up with. A tile with no colored pipe stays as it is.
The pipes act as the reference for every tile, so the colors have to match exactly. When all of the tiles are correct, you will see "Congratulations." That message confirms the puzzle is complete and unlocks the Weird Machine.
Craft the Skull Guitar at the Weird Machine
Head to the Weird Machine at Haunted Castle, which opens to you once the tiles are set. The machine stays closed until the puzzle is done, so the materials only matter at this last step. Craft the gun with these items:
- 500 Bones
- 250 Ectoplasm
- 1 Dark Fragment
- 5,000 Fragments
Gather all four before you reach the machine, since the craft needs every item. Once you have the Skull Guitar, its strong attacks, large hitboxes, and area damage make it useful in PvP and for grinding.
