TAKE COVER!! You only need to take a look at Wally Warhead’s face on the front of the packet to know you are in for a sour treat. Try them if you dare or better yet, trick a friend into trying one and watch as they struggle to contain the power of sour. This hard candy sweet comes in Watermelon, Blue Raspberry, Lemon, Black Cherry and Green Apple – more than enough ammunition to keep you going.
