Prince of ballads Sung Shi Kyung has made a shocking transformation.

Sung Shi Kyung made an appearance in his Avatar costume on 23rd broadcast of KBS 2TV 'YHY's Sketchbook'.

Sung Shi Kyung, who always maintained his serious and gentle image in the past, put the audience in shock with his new 'look'. He has his face painted blue with reggae hair and color contacts; and of course, the pointy ears.

On the other hand, Lucid Paul, IU, Jung Yeop, John Park, Sweet Sorrow, and others other made their appearances on this day's broadcast.
