As you play through the game, you will be able to equip stink bombs. These can be found laying on the ground, can be purchased at the comic book store, or can be made in your bedroom once you pass Chemistry 1. Once you have them, peg 50 people with them. To equip, hit or . to lock on a person, and to throw them.
Pulling the alarm in the boy's dorm and letting loose also helps a lot.You do not need to hit a person for it to count. It counts the amount of people in the stink cloud. So you can throw one bomb and have it count for 6 or 7 people if aimed correctly in a crowded area.
**You can check how many stink bombs you have thrown:**
