Airheads Extremes are sour. Like really sour. No really, they're really sour. As a result, they're not for everybody. Luckily, you don't have to choose whether or not to eat them, because the candy chooses who is worthy of it. In this campaign, we see how. 

Airheads Xtremes - "Slurpee"

Airheads Xtremes - "Raspberry"
