Four innocent-sounding candies. But each one has a trick. One is very sour, another will stain your mouth, another will foam in your mouth. And one will do all three. Each tube of Prank Powder Decepti-candy sounds harmless and lovely. But each label is deceiving. While the inner label sounds as innocuous as a baby tribble on valium, the outer label tells you what each candy is capable of. Bwaahaahaaaaa.
