This week on Yimugi Becomes a Dragon Race, BTOB's Yuk Seong Jae and WJSN's Kim Ji Yeon join as special guests. Across Seoul, magical pearls of various ranks, sizes, and shapes, lost by nine yimugis, are scattered, waiting to be found. In teams of two, they must track down and collect these pearls to amass the highest magic pearl level and claim victory. But teamwork alone won't be enough. Each person must also secure a pearl for themselves to escape the penalty. (thetvdb.com)
