If you’re going for 100% achievements in Servant of the Lake, the good news is that you don’t need to worry about some huge collection of missable story requirements. The game has a much nicer system: each level has its normal story achievement, plus a hidden achievement that usually comes from doing something strange, clicking something you wouldn’t normally click, or deliberately messing with an otherwise ordinary task.
That’s where things get interesting.
A lot of these achievements are easy once you know what the game is asking for, but some are incredibly easy to miss because there’s no obvious reason to try them during a normal playthrough. I’ve put everything below in level order so you can work through Day 1, Day 2, and Day 3 without jumping all over the place.
There is also a special achievement, You’ve Found Him!, which requires revisiting several earlier levels and completing a hidden sequence. I’ve put that at the end so you can deal with it separately.
Servant of the Lake Walkthrough – Beginner Guide, Achievements
There are nine hidden achievements to collect during Day 1.
1. Pet the Horse
This is one of the first secrets you can grab.
During the first morning, interact with the horse outside the estate.
Keep clicking and rubbing the horse’s eyes several times rather than moving on after the first interaction.
Eventually, the horse reacts and the achievement unlocks.
How to unlock:
- Go to the horse during the first morning.
- Interact with it repeatedly.
- Keep rubbing/petting its eyes.
- Wait for the horse’s reaction.
Achievement: Pet the Horse
2. Cat’s Extra Meal
This one is easy to miss because the milk is useful for more than one thing.
Find the box to the left of the maid and collect the milk.
Normally, you might simply continue with the story and use the milk where you’re expected to. Instead, take it to the cat first.
The cat is sitting on the chair in the living room.
Give the milk to the cat before feeding the mouse.
How to unlock:
- Find the milk in the box beside the maid.
- Return to the living room.
- Find the cat sitting on the chair.
- Give the milk to the cat.
Achievement: Cat’s Extra Meal
3. Move Along with Aldous
When you’re helping Aldous exercise, the game expects you to follow the exercise properly.
For this achievement, do the exact opposite.
Start clicking randomly during the exercise instead of following the intended sequence. Keep doing it until Aldous strains his back.
It sounds mean, but that’s exactly what you’re trying to make happen.
How to unlock:
- Start Aldous’ exercise.
- Ignore the normal sequence.
- Click randomly instead.
- Continue until Aldous gets stuck/strains his back.
Achievement: Move Along with Aldous
4. Minor Repairs
You’ll eventually receive the feather duster and be asked to clean the paintings.
Before simply dusting everything and moving on, head into the servant’s room.
Look for the small painting hanging there.
Click it repeatedly until the painting falls off.
Once it has fallen, interact with it again and repair/reassemble it inside its frame.
How to unlock:
- Obtain the feather duster.
- Go to the servant’s room.
- Find the small painting.
- Click it several times until it falls.
- Repair the painting.
Achievement: Minor Repairs
5. Bouquet Destroyer
This achievement requires you to be slightly destructive with something you’ve just spent time making.
First, complete the flower puzzle and create the bouquet.
Instead of immediately giving the bouquet to Alexandra, take it to the goat/sheep.
Let the animal chew on it.
Afterward, take the bouquet to Alexandra.
How to unlock:
- Complete the flower puzzle.
- Pick up the finished bouquet.
- Give the bouquet to the goat/sheep.
- Let it chew the bouquet.
- Give the bouquet to Alexandra.
Achievement: Bouquet Destroyer
6. Special Matcha Latte
Once you’ve obtained the tea leaves and prepared Alexandra’s tea, don’t immediately finish the task.
Look around the area near Alexandra and you’ll find a strange green powder in a container/basket near the back door.
Pick it up.
When making the tea, add the green powder to it.
You can add it either before or after Alexandra breaks the cup, depending on where you are in the sequence.
How to unlock:
- Obtain the tea leaves.
- Find the strange green powder near the back door.
- Pick it up.
- Add the green powder when preparing the tea.
Achievement: Special Matcha Latte
7. Baby Soothing Trick
During the reunion sequence, you’ll eventually obtain a bottle of wine/champagne and use it for Aldous.
Don’t put the bottle away once you’re done.
Use the bottle on the baby in Alexandra’s arms.
That’s the entire trick.
How to unlock:
- Obtain the wine/champagne bottle.
- Pour the drink for Aldous as required.
- Use the bottle on the baby Alexandra is holding.
Achievement: Baby Soothing Trick
8. Uninvited Guest
This one is particularly easy to overlook because the character you’re looking for doesn’t appear every time in an obvious way.
During the night patrol, check the windows and corridors carefully.
A mysterious person wearing a raven mask can appear near the back door.
When the figure appears, don’t immediately leave.
Observe them.
That is enough to trigger the achievement.
How to unlock:
- Begin the night patrol.
- Check the area around the back door/window.
- Wait for the raven-masked figure to appear.
- Observe the figure.
Achievement: Uninvited Guest
9. Scare Away Crows
The attic has another small secret.
When you’re searching the attic, keep an eye on the windows.
A raven/crow can appear outside.
If it doesn’t appear immediately, leave and re-enter the area a few times until you see it.
Once the bird appears at the window, click on it.
It will fly away and the achievement will unlock.
How to unlock:
- Enter the attic.
- Check the window.
- If no crow appears, leave and return.
- Repeat until the bird appears.
- Click the crow.
Achievement: Scare Away Crows
Servant of the Lake Day 2 Hidden Achievements
Day 2 has another eight hidden achievements, and several of them are tied to tasks you’re already doing for the main story.
10. Aldous’ Beloved Coffee
When you obtain the coffee bean/seed, don’t immediately process it in the normal way.
Take it to the fireplace in the servant’s room and roast it first.
Once roasted, continue with the coffee-making sequence as normal.
How to unlock:
- Obtain the coffee bean.
- Go to the fireplace in the servant’s room.
- Roast the coffee bean.
- Continue preparing Aldous’ coffee.
Achievement: Aldous’ Beloved Coffee
11. Tickling William
William can be tickled before he wakes up.
Use the feather you have collected and interact with William’s face.
Keep tickling his face/nose and chest until he reacts and tells you to stop.
How to unlock:
- Find William before he wakes.
- Equip/use the feather.
- Tickly his face and chest repeatedly.
- Continue until he reacts.
Achievement: Tickling William
12. Thorough Cleaning
This one is hidden inside the cleaning task.
When you’re cleaning the bloodstains in the servant’s room, look toward the upper-left area.
You’ll see three small line drawings of people.
Take your brush and move it over the drawings repeatedly.
Don’t just click them once. Keep rubbing the brush across the drawings until the achievement triggers.
How to unlock:
- Get the brush.
- Go to the servant’s room.
- Find the three small drawings.
- Brush over them repeatedly.
Achievement: Thorough Cleaning
13. Perfect Hunt
This achievement is much less forgiving than the normal hunting task.
When you go hunting, you need to kill every animal on the list without missing a shot.
In other words, don’t waste ammunition and don’t shoot wildly.
Check the hunting list as you go. The animals should all be marked off once you’ve successfully hunted them.
How to unlock:
- Start the hunting section.
- Hit every target.
- Do not miss any shots.
- Complete every animal on the list.
Achievement: Perfect Hunt
If you miss, it’s safer to replay the level rather than trying to continue and hoping the achievement will somehow trigger later.
14. Locks You See Is What You Get
This is one of those achievements where the game rewards you for being nosy.
Go upstairs and find the bathroom door.
Instead of trying to open it normally, interact with the keyhole.
Wait for the complete animation.
Something unexpected will appear, triggering the achievement.
How to unlock:
- Go to the bathroom.
- Click the keyhole.
- Wait for the animation to finish.
- Watch what appears.

Once you’ve cleaned the required sections, the achievement will unlock.
How to unlock:
- Wait until Alexandra has taken her bath.
- Look at the window.
- Clean the six small squares.
Achievement: Clean Windows
16. Garbage Disposal
There’s some rubbish that needs to go somewhere, and apparently the balcony is the perfect place.
Head to the balcony near the bathroom entrance.
Find the three pieces of garbage.
Drag each one onto the railing and throw it over the balcony.
Do this for all three pieces.
How to unlock:
- Go to the balcony.
- Find the three pieces of garbage.

17. One Shot Kills the Mouse
This is one of the more involved hidden achievements on Day 2.
You’ll need both the hammer/sledgehammer and the magnet.
Go through the leftmost door and find the mouse hole.
Use the magnet on the hole.
The first time, you’ll pull out a key.
Use the magnet again.
This time, the mouse comes out.
Wait for the mouse to run toward the centre.

Servant of the Lake Day 3 Hidden Achievements
Day 3 continues the same formula, with another set of hidden interactions that are easy to overlook during a normal playthrough.
18. Leisurely Petting the Cat
After finding the kitten, you’ll see it being held by the maid.
Don’t simply continue with the story.
Interact with the kitten repeatedly.
Keep petting it until it eventually gets tired of you and escapes.

- Find the kitten.
- Wait until it’s sitting on the maid’s lap.
- Pet it repeatedly.
- Continue until the kitten escapes.
Achievement: Leisurely Petting the Cat

Give the completed elixir to the parrot.
The interaction will trigger the achievement.

- Find the parrot.
- Give the elixir to the parrot.
Achievement: Animal Experiment
20. Inspecting the Furniture
There’s a secret hiding underneath the table in the servant’s room.

A note/letter will fall out.
Click the note to trigger the achievement.

- Click the second leg from the left.
- Pick up/read the note that falls out.
Achievement: Inspecting the Furniture
21. Adding a Spicy Topping
This is one of the stranger achievements in the game, which is saying something for Servant of the Lake.
While you’re preparing the food, you’ll notice a fly flying around the cake.
The maid gives you a knife.
Use the knife to kill the fly.
Then add the fly to the soup.
The achievement doesn’t necessarily unlock immediately. Continue through the sequence until the later hallucination scene, where a fly-man appears.
That’s when the achievement should trigger.

Move the fish into the correct position corresponding to William’s portrait.
Once you’ve placed it correctly, obtain the fish brooch.
Then, while talking to William, put the brooch on him.

23. Security Test
This one can be done almost immediately after entering the dining room.
Look toward the upper-left corner.
You’ll see a rope hanging there.
Keep clicking the rope.
Don’t stop after one or two clicks. Continue until Aldous reacts and opens his mouth.
That reaction is what triggers the achievement.

How to Unlock “You’ve Found Him!” in Servant of the Lake
Now for the achievement that’s considerably more complicated.
You’ve Found Him! isn’t something you can simply trigger by clicking one object in one level.
You need to revisit several earlier levels and enter specific information before the final step becomes available.
The sequence below is the important part, so I recommend doing it in exactly this order.
Step 1: Finish the Game and Continue
First, complete the game and reach the credits.
After the credits, choose Continue.
Read the note that appears.
This gives you the information needed to begin the hidden sequence.
Step 2: Return to Day 1 — Aldous’ Awakening
Go back to:
Day 1 → Aldous’ Awakening
Set the time to:
4:05
Make sure the time is entered correctly before moving on.
Step 3: Return to Day 2 — Bathing Assistance
Next, replay:
Day 2 → Bathing Assistance
You need to select four specific tiles:
- Alexandra
- Bath
- Suitcase
- Cut Off Hand
Make sure all four are selected before leaving the level.
Step 4: Return to Day 3 — Alchemy Assistance
Now go to:
Day 3 → Alchemy Assistance
You’ll find a box on the floor.
Interact with it and enter the following directional sequence:
→ → → ← → ← → → ←
Follow the sequence exactly.
Step 5: Return to Day 1 — Attic Search
Next, return to:
Day 1 → Attic Search
Find the box on the left.
The star counts, from left to right, are:
4 → 2 → 3
Enter the combination and continue.
Step 6: Return to Day 3 — Dressing for Dinner
Now go to:
Day 3 → Dressing for Dinner
This is where the final part of the puzzle comes together.
Head into the cellar.
You need to arrange the three wine bottles in their correct positions.
The bottles are identified by the rings around them:
- Gold ring bottle: Lower level, center triangle pattern — first position from left to right.
- Silver ring bottle: Upper level, S-shaped pattern — second position from left to right.
- Bronze ring bottle: Upper level, vortex pattern — third position from left to right.
Once the bottles are arranged correctly, the top wine barrel opens.
Enter the barrel and you’ll find a shelf.
Step 7: Enter the Telescope Combination
Look for the green combination lock in the centre of the cabinet.
Enter:
6294
The cabinet will open and you’ll obtain the telescope.
This is the item you’ve been working toward through the previous steps.
Step 8: Find Him With the Telescope
Now leave the cellar and head toward the window near the dining room/restaurant entrance.
Open the window.
Use the telescope and look toward the distant building on the mountain.
Focus on the window/building in the distance.
You’ll eventually see a black figure on the second floor.
Click on the figure.
That’s the final trigger for the hidden achievement.
Achievement: You’ve Found Him!
