缩小我的室友以吞下他

My roommate usually eats my snacks and drinks from my fridge when I'm not close around, until I catch him at the crime scene! We argue and I threaten to find another roommate if the situation persists, however I still don't trust him so I add a few drops of shrinking potion to my isotonic water. When I go to take something to quench my thirst, I realize that the lid is on incorrectly. I confront my roommate, laughingly confessing that he has taken a shrinking potion while I see how slowly he shrinks in size until he becomes sleepy. When finally opens his eyes, realizes that now is small enough to be devoured the same way he eats my snacks. But before, i want to have some fun with my new mini-toy-men.
