Inside the Engineering Wing in Poppy Playtime: Chapter 5, you'll come across a puzzle involving a combination-locked locker where you'll have to get the content from the locker to proceed through the level. Here is the solution to this puzzle.

The Engineering Wing is a level in Poppy Playtime 5 you'll get to after meeting the second NPC ally, Chum Chompkins, and after helping him and Giblet for a bit, you'll get separated from them. Once you do, you'll get inside the Engineering Wing and a very hard and interesting puzzle to solve.

Once you enter this place, look for a blue pallet and climb it to enter the second, more spacious room. Here in this room, this puzzle takes place; however, to reach the locker that needs a code to be opened, you'll have to do a little rearranging in this room first.

How to Reach the Locker Room

The locker room is located on the second floor of the room you entered by jumping over the blue pallet. This room is very big and enemy-free, so you don't have to worry about one of them jumping you or anything. You'll notice a lot of crates you can push and pull in this room, but your priority should be two big ones.

One of the big crates is located in the part of the room with some debris; make sure to push it using the pressure glove to go in between two piles of debris. Arrange the crates the way you see in the picture below, then jump on the debris, and from crate to crate, jump on the broken catwalk in the middle of the room.

How to Find the Combination for the Locker

Once you jump on the catwalk, keep going forward until you see two yellow-red boxes – behind those boxes is the battery, so make sure to pick it up and continue over the catwalk to enter the room on the other side. Inside this room is a locker; however, to power up the keypad, you'll have to first install the battery inside the slot, which is located behind the second set of lockers, just next to the keypad.

Once the battery is in place, it's time to discover the correct combination code. On the opposite side of the room, you'll see a whiteboard. Use the black light to see a hidden message on the board, but first, flip the board over using one of the hands. The message on the board will be 99 - TF. There will also be the second arrow drawn on the window, pointing to something on the lower floor.

If you make your way back to the ground floor, you'll be able to find a crate labelled '99 - TF', and on that crate is the number 782; that number is the code you must enter to unlock the locker and pick up its content. Now, return to the upper floor and enter the code inside the keypad; the middle locker will open, and you'll be able to pick up a new upgrade for your hands called "Emu Cuffs".

Emu Cuffs will allow you to stick to any magnetic surface and add a new ability to your traversal arsenal. This upgrade will allow you to leave this room and proceed further through the game.
