I was trying to figure out the purpose of this distinguishing feature made up of red, fleshy, wobbly skin that makes up the comb, waddle and ear lobe.  Thanks to the book Bambi gave me for my birthday I learned that they can not sweat and the only way their body cools off is with the help of blood that pumps through this exposed skin.  As much as I love to snuggle them, as above, I should probably refrain from wrapping them tightly in furry blankets that could cause them to overheat LOL
