The factory door opens only when you have done your job.
Factory workers use time clock to tell they are done.
You should first talk to the mystery guy. After that there is the time card. You have to get out.
Get the time card next to the time clock and punch it in the clock.
You need to make holes into it.
There is the vampire platypus with sharp theeth. Go show the card to it and it will open the holes.
Nice, and you got yourself some garlic.
