It is likely that, when you click on continue on the warning screen, Germany will appear scaring you.

Poland may be replaced by an endoskeleton in the game menu (this replacement only passes one of the 20 possible combinations)

if it's night 3 activate this cheat. if it is 3 am you should go to camera 10 and press 3 on your keyboard, if you did it right the European union will appear in your office.

PD: this character is impossible to avoid.

if you touch Germany's eye it will squeak.

PD: this can be done both in the office and in the extras.

If you put specific numbers in the custom night, a minigame could appear. (there are 4 mini-games in total)

PD: these numbers appear in previous gamejolt posts (you should find out more about me and maybe you will find some numbers in some old post).

If you manage to pass the 4 minigames, a secret scream will appear and an ending that will give you the third star.

PD: This third star is also achieved by passing the 7/4 challenge.

if you click on the third star it will take you to a secret minigame to get an option to see the cinematics and play the minigames as many times as you want.

Five nights with Poland is as super Mario 64 XD.
