Six year-old twins Zony and Yony are set to release an album, a DVD and a book.

They have also filmed a music video, which features the elementary age-twins playing on Fulong beach and writing calligraphy at Tainan’s Confucius Temple.

Zony and Yony made headlines in Taiwan in February, after a video of them wearing pink motorcycle helmets, pink jackets and rainbow leggings and dancing to “Bar Bar Bar” by Korean girl band Crayon Pop went viral.

The pair also shot to stardom in the U.S. in May, after making two appearances on the Ellen DeGeneres Show in as many weeks, performing Justin Bieber’s “Baby” and Crayon Pop’s “Bar Bar Bar.”
