But I don't exactly know how to make player sneeze, but Maybe if there was a timer in player script where it resets every 2 minutes and when it resets the sneeze sound plays and triggers baldi's hear function, but i'm not sure.

i have an idea with the "Sneeze" for error flower, when error flower has close of the player, she make player sneeze, because the player is "alergic"
If flower now make player sneeze, so, she have other name: Alergic Flower
Edit: But it looks like this function is similar to the 2-head Baldi function
