You’re home doing your morning routine, until a news broadcast reports a rapidly spreading virus: the Weight Gain Virus. Those infected by it gain weight, and pass it on by burping or getting into close contact with the un-infected. They also eat food, and never get full, and just keep eating and eating and eating, getting fatter and fatter and fatter as they go, but they don't care; the virus makes them enjoy it and think that it's good for their bodies. You only have one simple goal:

DON'T GET INFECTED.

You are in your home currently, and it is the morning, 8:00 am.
