The group, known as Bulldok since their trainee days on the Mnet show under KCONIC Entertainment, impressed many with their unique color and distinctive image. In addition to Kim Min Ji, Kim Hyung Eun, Park Sae Hee, and Lee Jin Hee, who were on 'Produce 101', Bulldok will be adding a fifth member - a trainee from GON Entertainment with whom KCONIC will be partnering up with - named Park So Ra. 

Bulldok plan to emphasize a girls hip-hop image similar to their 'ssen-unnie' style on 'Produce 101'. They'll be holding their debut showcase this October 20 at Seoul's Hongik University. 

Another eye-catching factor about Bulldok is that two of their members have celebrity siblings. Lee Jin Hee is the cousin of Antenna Music singer and former 'K-Pop Star 4' contestant Lee Jin Ah, while Park Sae Hee is the biological younger sister of Topp Dogg's leader P-Goon.
