In the central security office you watch the four monitors for the repeating code, past this door you'll find a collectable and a film reel - Don't forget to come back to the bathroom later with the Executive clearance

2 6 2 9 4

In this area on NG+ I knocked out the first set of clown teeth and six on the next set, then walked around the counter and crawled through to enter a back area that lead to the Storytime Showroom, but a door was locked with Lv4 Security


Once you get the level four security upgrade, return through the welcome show at the entrance and take the elevator up to the showroom (Or take the admin path through the warehouse), however from the showroom lobby I could simply enter through the left side shown here. If this isn't open to you just power on the area again by the ticket booth and you can play the clown game

This first code is four digits, I just entered them in a revolving order until I got the correct one - 4782

This will take you back to Jackie's area



When you find the second keypad in the new area, enter the vent and check the monitor like the last two times

Hint: The same coloured blocks
Code: 0434



Inside this room make sure you use both levers, this will reactivate the elevator so you can come back up from storage instead of the birthday showroom

Through the area are mailboxes, the files (marked clearly as Admin) go through days of the code being changed around, so make note of the date and time and work the number out

I'm not putting screenshots of each note but I'll put a screenshot of what the mailboxes look like in case you've been missing them

Code: 01350
Solution:
December 1st - 12:30PM (Code is set to 49762)
December 2nd - 4:13AM (Bob adds 300 making it 50062)
December 2nd - 4:18AM (Wally changes the first two digits to 29)
December 3rd - 3:05PM (Penny changes the first two digits to 21)
December 4th - 8:19PM (Bob changes the first two digits to 01 because he's #1)
December 4th - 8:34PM (Penny changes the last two digits to Bev's age which is 50)
December 5th - 5:00AM (Bob adds another 300 to the code)
Leaving you 01350

Thank you to The Milkman for pointing this out to me, I missed it on my first playthrough

When gain the final security upgrade and return to the starting area with the security room you can go open up the door facing away from the security room and find a monitor displaying a code

Note: To figure out the order you'll collect the mail in the real area and check the static monitors


Make your way back to the welcome show and enter the main lobby, head up and the stairs and enter the Retail Showroom where you will find the keypad in the back near the merry-go-round

Code: 80625

Enjoy what you find past the code

I am unsure if you truly need all 25 of 25 collectibles but it's safer to grab them all before trying this. When you are going through Moon.Exe most options are actually safe to use but if you die you don't fully restart so don't stress!
