another theory: On jolly 3 chapter 2 we found spring trap and it's actually a trap because kevin Johnson and William afton worked together to trap the main character

HAPPY 8TH BIRTHDAY FNAF:D

True

This is a theory

The elevator from J3C2 is actually a trap That kevin Johnson made and he make the elevator collapsed making the main character (possible Thompson from jolly 2) injured and the good time animatronic is a trap

But that just a theory

Guys i think jolly 4 gonna release on 2023
