Group Crayon Pop will be releasing a Christmas carol song at the end of this month.

Today, they released teaser photo of the members dressed up as Christmas trees, making fans excited for their new song.

This carol was also written by the same composer who wrote their hit song, "Bar Bar Bar" and has gained much attention.

On the other hand, Crayon Pop will be holding a collaboration stage with group Ylvis at the 2013 'MAMA' in Hong Kong.
