Trying to unlock Festering Felix in Roblox The Hollow? The third-floor challenge requires you to solve a gravestone puzzle by checking eight tombstones and working out the correct three-symbol combination. The trick is to calculate how long each person lived and use the three shortest lifespans to determine the code.
This puzzle can be confusing if you try to guess the answer or enter symbols randomly. Each tombstone has different dates and a symbol, and you need to compare all eight before deciding which three matter. The correct answer can also vary between players, so copying another person’s code might not work in your game.
In this guide, you’ll learn how to find the eight tombstones, calculate the ages, identify the three youngest people, and enter the correct symbols to complete the puzzle and unlock Festering Felix.
How to Get Festering Felix in The Hollow – Floor 3 Gravestone Puzzle
First, explore the third floor of The Hollow until you find the room containing the gravestone puzzle.
Once you enter the room, you will see the puzzle instructions and need to investigate eight tombstones scattered around the map. Each tombstone contains information that helps you solve the challenge.
Do not worry if the tombstones are spread across different areas. You can visit them one by one, record their information, and return to the puzzle once you have worked out the answer.
The important thing is to check all eight tombstones rather than stopping after finding a few.
How the Gravestone Puzzle Code Works
The objective is to identify the three people who died at the youngest ages. Their tombstones provide the symbols you need to enter into the puzzle.
Each gravestone has two dates:
- Birth year: The year the person was born.
- Death year: The year the person died.
Subtract the birth year from the death year to calculate the person’s age at death.
Use this formula:
Age at death = Death year − Birth year
Once you calculate the ages for all eight tombstones, arrange the results from youngest to oldest. The three smallest ages determine the order of the symbols you need.
Step 1: Check All Eight Tombstones
Start by finding each of the eight tombstones around the map.
For every grave, write down the person’s name, birth year, death year, and the symbol displayed on the tombstone. Using a notepad makes it much easier to keep everything organized.
You can use a simple table like this:
| Tombstone | Birth year | Death year | Age at death | Symbol |
|---|---|---|---|---|
| Grave 1 | Record year | Record year | Calculate | Record symbol |
| Grave 2 | Record year | Record year | Calculate | Record symbol |
| Grave 3 | Record year | Record year | Calculate | Record symbol |
| Grave 4 | Record year | Record year | Calculate | Record symbol |
| Grave 5 | Record year | Record year | Calculate | Record symbol |
| Grave 6 | Record year | Record year | Calculate | Record symbol |
| Grave 7 | Record year | Record year | Calculate | Record symbol |
| Grave 8 | Record year | Record year | Calculate | Record symbol |
Fill in the information as you visit each grave. Once all eight are recorded, you can compare their ages and identify the correct three.
Step 2: Calculate Each Person’s Age
For each tombstone, subtract the birth year from the death year.
For example, one gravestone might show that a person was born in 1892 and died in 1914.
1914 − 1892 = 22 years
That person lived for 22 years.
Another tombstone might show a birth year of 1794 and a death year of 1844.
1844 − 1794 = 50 years
That person lived for 50 years.
Repeat this calculation for every tombstone. You should end up with eight different ages to compare.
Be careful when reading the dates, as using the wrong year will change the result and could lead you to select the wrong symbol.
Step 3: Find the Three Youngest People
After calculating all eight ages, arrange them from the smallest number to the largest.
You only need the three smallest ages to solve the puzzle.
For example, imagine your results look like this:
| Person | Age at death | Order |
|---|---|---|
| Person A | 22 | First |
| Person B | 27 | Second |
| Person C | 31 | Third |
| Person D | 38 | Fourth |
| Person E | 44 | Fifth |
| Person F | 50 | Sixth |
| Person G | 57 | Seventh |
| Person H | 63 | Eighth |
These numbers are just an example to demonstrate the method, not the actual answer for every player’s puzzle.
In this example, the three youngest people are Person A, Person B, and Person C. You would then find their tombstones and use the symbols displayed on those graves.
Remember, you are looking for the youngest ages at death, not the earliest birth years or the most recent death years.
Step 4: Record the Three Symbols
Once you have identified the three youngest people, return to their tombstones and check their symbols.
Write down the symbols in the same order as their ages:
- The symbol belonging to the person with the lowest age.
- The symbol belonging to the person with the second-lowest age.
- The symbol belonging to the person with the third-lowest age.
For example, your combination might contain a spider, a bat, or other symbols displayed on your selected tombstones. The exact symbols depend on your puzzle, so use the ones shown in your own game.
Do not enter the symbols in the order you found the graves. Their order must follow the three shortest lifespans.
Step 5: Enter the Code and Unlock Festering Felix
After recording the three correct symbols, return to the gravestone puzzle room.
Enter the symbols in order, starting with the person who lived the fewest years and finishing with the person who lived the third-fewest years.
Before confirming your answer, double-check your calculations and make sure each symbol belongs to the correct tombstone.
If the combination is correct, the puzzle will unlock and allow you to progress toward the Festering Felix reward.
If it does not work, revisit all eight tombstones and check for a misread date, an incorrect calculation, or symbols entered in the wrong order.
Common Mistakes to Avoid
Checking Only Three Tombstones
You need to calculate the ages of all eight people before you can be sure which three are the youngest. A grave that initially looks like a good candidate might not belong in the final combination.
Subtracting the Dates Incorrectly
Always subtract the birth year from the death year. Reversing the calculation will produce the wrong result.
Using Birth Years to Determine the Order
The puzzle is based on how long each person lived, not when they were born. Calculate each person’s age at death before comparing the results.
Entering the Symbols in the Wrong Order
Even if you find the correct three graves, the sequence matters. Start with the shortest lifespan, then the second-shortest, and finally the third-shortest.
Copying Another Player’s Code
The puzzle answers can vary between players. Use another player’s explanation to understand the method, but check your own tombstones to determine the actual combination.
The Floor 3 gravestone puzzle in Roblox The Hollow is much easier once you understand the clue. Find all eight tombstones, record their birth and death years, calculate each person’s age, and select the three shortest lifespans.
After that, collect the symbols from those three graves and enter them in the correct order. You do not need to guess the code or test random combinations when the tombstones provide all the information you need.
Follow these steps carefully, and you will have everything you need to solve the gravestone puzzle and progress toward unlocking Festering Felix.
