The Old Po Awareness Meter is a vital mechanic in Five Nights at Tubbyland 2.
It shows as a small white transparent bar in the bottom right corner of the screen, with the words, 'OLD PO AWARENESS' above it. As the bar fills with gray, it turns into a yellow when it is almost full. It turns into a red when it is full.
This mechanic works that when you move, turn on the smoke machine, or put up the monitor when Po is close to your office, the meter will go up and make Po aware of the noise coming from the office. If it gets full all the way, you get killed by Po.
- The mechanic was not in anyway inspired by the One Night at Flumpty's 2 exposure meter, both ideas had been thought of already, but ONaF 2 had come out first.
- This caused confusion and many people accused Critolious of stealing ideas, then Jonochrome (the creator of One Night at Flumpty's) confirmed the games were at work during the same time, and no idea theft was going on.
- Originally, The Old Po awareness meter had only said "Awareness". The meter changed its text to "Old Po Awareness" to prevent confusion in the game.
