The festival attracts lots of tourists and boosts the local economy. Supposedly, the mud in Boryeong is rich in minerals and moisturizes the skin. True or not, the locals have advertized the festival as a fun event where people can play, have fun and get crazy. If you don’t believe me, watch this video :

The mascots of the festival are people covered in mud. When you see the mascots, you’ll know the festival is in progress.
