The Beanboozled Challenge from Jelly Belly has 20 distinct flavors. The jelly beans come in identical-colored pairs. One of each pair is a sweet candy-flavored bean, while the other bean has an offensive taste.
Flavor pairs include peach and barf, buttered popcorn and rotten eggs and juicy pear and booger. The challenge comes in a special box with a spinning wheel to select a flavor combination. Jelly Belly also posts a spinning wheel on its website.
Inspiration for the offensive flavors comes from the Bertie Botts Every Flavor Bean line of products of the "Harry Potter" book and film series. Jelly Belly's original 50-flavor line provides the sweet flavors.
