As a platformer and a collect-a-thon, PaperKlay is a game that rewards the observant player, finding alternative routes to reach a location, or spotting hidden collectibles tucked away in each level. But for the A Peek Inside Can’t Hurt! achievement, we will be looking for clues. There is a vault door found in one of the hub worlds, and we are going to bust in! So, here is our A Peek Inside Can’t Hurt! Achievement Guide to help you crack this safe!
Read our full thoughts on the game with our PaperKlay Review.
To unlock the A Peek Inside Can’t Hurt achievement, you will need to have reached World 3, the Pirate Cove.

From where you start, you want to head forward to the cardboard-lined hole in front of you. Inside this cave is the vault door we are looking for, with three valves in front of it.

Standing nearby is Dr. Fuzzitail, who will explain that there are clues dotted around the world to help solve the code for the vault.

Thankfully, the first clue is in the very room you are in! Look on the wall opposite the vault door to find the clue to the middle ring, which is the number one (1).

The other two clues are found on the surface, so leave this cave. We’ll return when we have the other clues.
The next clue can be found inside the giant skeleton, which is pretty hard to miss.

Climb up the land platforms and use the shipwreck to glide across to the barrel the skeleton is holding. From here, you can walk inside its mouth.

Inside is a strange room made up of barrels, it seems. Tucked away at the back is the second clue, stating the innermost ring must be set to the number four (4).

Exit the skeleton’s mouth and make your way onto the piece of wood they are holding, where you will also find an egg! From here, you can glide over to where the last clue is hidden.

Scrawled on the rock wall is the final clue, telling us that the outermost ring should be set to the number three (3).

Head back into the cave with the vault inside, and hit the valves to spin the arrow around to point at the correct numbers. Once you’ve input the correct code, the vault door will swing open, and the Just A Peek Can’t Hurt! achievement will pop!

While there may not be any archeological finds for Dr. Fuzzitail, there’s more for you to explore, including access to the Goldfish Hills level!
