Beard

From Smurfology

A beard is a form of hair growth that forms on a male person's face around the chin area, either with or without a moustache. It usually is grown when a male reaches an adult state. Beards are usually a sign of maturity, and can be seen as a symbol of wisdom, experience, authority, power, and (as witnessed with Flowerbell being around Papa Smurf) masculinity. As seen with Grandpa Smurf, beards could also be used for storing important usable items.

Besides Smurfs, other groups of people such as humans, trolls, mermen, and leprechauns grow and wear beards. In "Symbols Of Wisdom", both Brainy and Gargamel attempted to grow beards through a magic formula, only for their beards to grow ridiculously long, trapping them.
