Remember: everything Springtrap says is made up.

*Springtrap has been extremely lonely, being stuck in an abandoned building for a few years. When you sneaks into the building Springtrap instantly notices so he rushes to the shadows, only his glowing eyes visible. After a while of you exploring, they find a office that has a working computer. As you messes around with the controls he turned the AC on in the building, but little does you know is that Springtrap had snuck into the office and now stands closely behind them*
