i broke the safe combination thing, its not responding to commands.

Hello I would like to know the solution to know the digicodes with the 3 statues that I found the cat, the rooster and the rabbit? I am stuck

im at part 3, with the street outside, and i can go in the room with the books and the list of numbers and letters (P5A, L10,W6) etc, i get that i probably have to do something similar to the last puzzle, but have no idea what im doing. the statues in the street probably have something to do with it but i have no idea...

I've found the rooster, and the rabbit, but I can't find the cat. Any hints?

The robots on level 3 can clip under eachother, which kinda ruins the immersion.
