When you imagine chocolate you may picture a creamy sweet treat, but with this latest challenge, things are heating up a bit! The Choco Challenge has people all over the world sampling the worlds spiciest chocolate bar for a good cause. For every Choco bar purchased, Fuego donates five dollars to prostate cancer research. The company has already raised over $69,780 of its $100,000 goal and people taking the challenge are really feeling the heat. But please be careful, if you have a sensitivity to spicy foods, maybe sit this challenge out.
