As a rule of thumb, you should never eat anything that's coming out of the inside of a toilet and you should definitely avoid eating said substance off of a toilet plunger. I think, however, this product is probably the one and only exception to this rule.
Sour Flush candies are in the same vein as Baby Bottle Pops, only instead of a candy rubber nipple, it's a candy rubber plunger and instead dipping into a baby bottle, you're dipping into the bowels of a plastic toilet. You can choose from Sour Apple, Blue Raspberry or Watermelon flavors. Bon appetit FOODBEASTs!
