Kindergarten

Take $3.00 and start the day
Buy a yo-yo, cigarettes and a screwdriver from Monty

Morning Time
Go to Jerome and show him the yo-yo so he will be your morning buddy
Take the hall pass from him and start the distraction
When you’ve left the classroom and have shown the pass, go into The Janitor’s closet
Inside, you will see a shelf with a box which has 'stolen stuff' written on it
Go to the left side of the shelf, an exclamation mark will pop up, unscrew the screw and the shelf with the stolen stuff box will fall down.
Now grab the laser pointer out of the box and go straight to the exit
You will get sent back to class and after a short conversation with Jerome lunch time will start

Lunchtime
After talking to Jerome quickly hide the laser pointer in the trash, so the janitor doesn’t find it
After the janitor takes the trash to the bathroom, go talk to Jerome
Jerome pays off The Lunch Lady if you agree, and you can go to the bathroom
Here you need your cigarettes so the monitor doesn’t send you to the principal
Get the laser pointer out of the bag next to the sink and go back to get sent out to recess

Recess
Talk to Monty, and get the device from him to free Jerome from The Janitor
Place it behind him and talk to Monty again, then The Janitor will explode

Show and Tell
Just don't die, and then Jerome will give you the Key Mold after show and tell
