what i meant to say was the 77 seconds bit is essentially worthless information. all that matters is after the 5th laugh she's positioned to attack and thats when you want to wait a moment and then keep the door closed. No one is going to count 77 seconds five times in a row while also dealing with foxy and bonnie. Chica is there but she doesn't really stick around.She laughs every 77 seconds 6 times. She gets you on the 6th. Just have your door closed by then...
