This guide will let you know how to get every single achievement for this game.
Guide to Get All Achievements
Looking for trouble
Once you start the game, you should peek the Courtyard, by looking through the cell window with bars that is behind you.
Once you crouch or jump to avoid getting hit by the imp guards the imp boss is throwing downstairs, click on the spider to turn the lights off, in order to defeat the imp boss. You should click on the spider after the boss throws 3 guards.
Sneaky Beaky Like
Do not ever let the imp guards nor the Wizard see you while you're crossing the castle battlements.
A Helping Hand
At the Camp, you'll have to switch the position of the target dummies as many times as you need to let the small imp guard win the game. Touching in the targets before the imps shoot them will make them to hit or miss. The small imp needs to win 3 rounds in order to get the achievement and keep the game story going.
A More Elegant Weapon Perhaps?
Try the weapons you'll find in the Armory by clicking in each of them.
Not Falling For This One
In the Sewing Room, try to touch the spindle.
A Game Of Cat And Mouse
At the outer side of the Guard Room, make the cat run after the crow, by shoo the crow away a few times. Do it while being closer to the tip of the pole, otherwise it won't work. Then, get back to the windows and click on the imp guard to make fun of him while being in one of the windows, once you click on him, move yourself to the opposite window. Do this a few times and the cat will appear, scare him and befriend you.
Quit Mousing Around!
After helping the cat in the Guard Room, go to the Pantry and pull the bell cord to call the cat. He will scare the mice away.
To Fail Is To Stop Trying
Use every wrong item on the Evil Fairy by the Great Hall. Do it right after the pocket at the bottom right of the screen shows back up (eventually when the Evil Fairy gets ready to attack you). This requires some patience, you must use and item at once, die, go back to the Great Hall and repeat it with another item. These are the items you should use, one by one, on the Evil Fairy: carrot, dragon scales, feather, mug, sticky web, gloves, boots and the two pieces of paper that belong to the elixir recipe (you may have found these items at this point already). The only item you should not use before getting the achievement is really the pepper shaker - that's the one that will make the Evil Fairy lose the battle.
You'll get this achievement once the Evil Fairy is defeated. Use the pepper shaker in it, in the moment the Evil Fairy gets ready to attack you. Leave the Great Hall while the Wizard is fighting the Evil Fairy.
Threading The Needle
Fix the damaged magic bag/torn magic backpack at the sewing table located in the Sewing Room.
Master Of Disguise
Once you place all the Golden Armor pieces in the Sewing Room mannequin, grab it, go to the Tower and wear the armor to trick the imp guard that you'll find there.
Read all the books (until the end) you can interact with at the Library of the Tower.
Trick Goldie, the Golden Imp guard on the stairs of the Tower with a bag of coins. After you throw him coins for the second time, click quickly on the rope that is holding the chandelier and let the magic happen ;). The bag of coins can be found inside the Library's drawer, under the mirror, but can only be opened once you manage to annoy the Wizard.
Quicker Than A Snail, Slower Than A Cheetah
This achievement can be obtained in the Tower mini-game, after tricking the Golden Imp guard. You'll have to finish this mini-game of going down the stairs without missing any of the buttons that will pop up in your screen meanwhile. So basically, do not fall down until the mini-game ends.
What Happens In The Dungeon, Stays In The Dungeon
Once the Wizard leaves his room at the top of the Tower, go to his room, then go back outside to the Courtyard and click on the window of the Dungeon, you'll find the Wizard in there.
Gotta Catch 'em All!
Find all the 3 thorn pieces of the elixir recipe page from an alchemy book. You'll find the first piece at the Dungeon: get back there once you can and watch the sewer monster grabbing the imp wizard, who will leave pages of his book behind, and Tsioque will eventually grab the first piece of the recipe. The second piece of the recipe can be found at the Guard Room in the wall with the poster. The third piece can be found at almost a late stage of the game, by the Wizard's room at the top of the tower. Just click on the crumpled paper on the floor, by the coal basket
Better Living Through Alchemy
Prepare the Elixir in the Wizard's room and pick it up. You'll have the recipe pieces at this point and use the book by the table to put them all together, so you'll have an idea of what to get and do in order to obtain the Elixir. For the Elixir, you'll need the following ingredients: Dragon Scales, Coal, Leaf, Feather, Golden Water and Earplugs. To create the Elixir, follow these steps, while looking at the second picture below: 1. Throw the Leaf in the fire and close the door; 2. Place the Dragon Scales and seal the flask with an Earplug; 3. Pour the Golden Water into the flask; 4. Open the first tap; 5. Place the Feather inside the flask; 6. Leave the bowl in the middle without the lid and use the air blower once; 7. Put the coal inside the bowl, and close it with the lid.; 8. Open the tap; 9. Use the air blower once again; 10. Place the other Earplug in the flask; 11. Use the air blower one more time. The formula should be dropping into the bottle at this point, otherwise click on the tap over it again and use the air blower until a drop falls into it. Pick up the Elixir.
Try pouring the Elixir into the Wizard's mug. Note: The Bottoms Up! and It's Not Stealing If It's Mine achievements are mutually exclusive, which means you'll need to play the game 2 times in order to unlock both achievements. You can only unlock the Bottoms Up! achievement if you did not try to steal the Medallion from the Wizard's belt before, in the same game (if so, you've unlocked the It's Not Stealing If It's Mine achievement and need to play the game a second time to do this Bottom's Up! achievement). OR you just do a backup of the saved game file before you perform the actions that will unlock one of the achievements (the file is named dat.xlg and you can find it at \SteamLibrary\steamapps\common\TSIOQUE) to somewhere else in your pc, then keep playing the game until one of those achievements is unlocked, and replace that current saved game file under the game directory by the previous one you've done a backup of and keep playing the game to unlock the mutual achivement and all the other ones you may still need.
It's Not Stealing If It's Mine
Try stealing the Medallion from the Wizard's belt. Note: The It's Not Stealing If It's Mine and Bottoms Up! achievements are mutually exclusive, which means you'll need to play the game 2 times in order to unlock both achievements. You can only unlock the It's Not Stealing If It's Mine achievement if you did not try to pour the Elixir into the Wizard's mug before, in the same game (if so, you've unlocked the Bottoms Up! achievement and need to play the game a second time to do this It's Not Stealing If It's Mine achievement). OR you just do a backup of the saved game file before you perform the actions that will unlock one of the achievements (the file is named dat.xlg and you can find it at \SteamLibrary\steamapps\common\TSIOQUE) to somewhere else in your pc, then keep playing the game until one of those achievements is unlocked, and replace that current saved game file under the game directory by the previous one you've done a backup of and keep playing the game to unlock the mutual achivement and all the other ones you may still need.
3, 2, 1... Transformation!
The reality needs to change, in order to unlock this achievement. It will happen once a disaster is triggered. You just need to keep playing and this will eventually happen when the time comes (specifically, moments after you try stealing the Medallion from the Wizard or pour the Elixir into his mug).
A Helping Foot
Once you go to the Courtyard after the disaster, you'll see a giant pair of boots at the left bottom of the screen. Click in one of the boots to set free an imp that was probably wearing them before the disaster happened.
Give Me A Kiss, Mallard!
After the disaster, go to the cave and offer the duck your Medallion. The duck is grumpy, so eventually the washing machine wire will drop because of him and you should click on it to climb the machine. Once you're closer to the duck, pull the chain. The duck will befriend you after a while.
Now With 3D Support
After the disaster, help the Teddy Bear by the Great Hall, by giving him a Little Black Button to replace his lost eye. You can find the button inside of the washing machine at the cave. The Teddy Bear will befriend you then.
Sucks To Be You
Escape from the Dragon. Use the Bubble Maker in his stomach acid pool, and quickly put the mace between the hole walls to get out of it. Let the Dragon vacuum himself and you'll unlock the achievement.
Set the Zebra free. Go to the Stables and hit the Zebra leash/chain with the Mace. The Zebra will befriend you.
Prepare tea for the Troll, the Princess and the Unicorn at the Kitchen. Previously, you'll need to find the 3 teacups. Find the Purple Teacup inside the Kitchen cabinet, right under the stove. The Pink Teacup can be found inside the giant slime by the Gallery. Grab the yellow Sieve by the Kitchen utensil hanger and use it in the giant slime to grab the cup. The Green Teacup is inside the toybox at the Stables. Start making the tea by: 1. placing the kettle in the sink and 2. fill it with water, 3. then put it back in the stove and click in the left stove knob and let it boil. 4. Once the water is hot enough, pour it into the teapot, 5. then pour the tea into the cups with the teapot. Grab the cups with the tea and serve each of them to the characters at the table.
Set the dog free from the giant slime. After serving the tea to the characters in the Kitchen, grab the Explosive Pebbles and click on the fridge and the Unicorn will open it for you. Grab the Black Sparkling Liquid and go to the Gallery. Use the Black Sparkling Liquid in the slime, followed by the Explosive Pebbles. After the explosion, the dog will befriend you.
After the slime explosion, hit the magic door in the Gallery with the Mace.
Death Wish 3
Try hitting the Wizard with the wrong item (use the Mace instead of the Mirror), as soon as he gets up from the throne and your backpack reappears at the right bottom of the screen.
And They Lived Happily Ever After?...
Finish the game by escaping the Wizard and the castle.
