Springlocks are a game mechanic in DSaF and DSaF 2. While wearing Cool Cat (DSAF) or Spring Freddy (DSAF 2) there are numerous actions you can preform; some of them result in a springlock failure where the player dies. Some examples of this are: in DSAF when the player tries to do a flip, in DSAF 2 if you preform the safety dance incorrectly, you will be springlocked. Springlocks is also how Jack or Dave becomes Springtrap.
