I don't know if Menthol candies do count as spicy, i mean they are in part sweet depending of the product.....though if it does kill them, which i hope it does, it would be quite a *puts shades on* Refreshing Death
As long as we can confirm this Deibu didn't get away with her shit without some degree of serious pain or better, painful death, i'm aok with whatever those candies are.
