hello!

Feeling a bit slow. can't figure out how to unlock the cyan toilet. also can't figure out what number to put into the non-coloured locked toilet. I think I've looked everywhere. I'm thinking it has something to do with the labels on the cardboard boxes but I can't figure it out. 

Would love a hint! Thanks for making the game.

Hi ElectricBurgers!

Cool name btw. :) 
I have not played the game for a while, so I cant remember.  I am going to check for you when I come home from university, and point you gently in the right direction :) 

All the best, 
Lasse Viking.

First hint:  some walls look more dirty than the others.

Second hint: There's a sign in the sink in the utility room. It looks like something of interest. 

Come back if you're still stuck, and ill elaborate :) 

Happy puzzling ;) 

Hope you got this solved. Can I ask a question as well please? I am stuck in the toilet where I have the cubicles with the three numbers on green orange and blue which I have solved. There is a green padlock on the next cubicle but I cannot find the green key and I cannot get through the next door that seems to have sort of intercom on it. Do you know how to do these two things please?
