Lee Byeong-Chun and scientists from Seoul National University and RNL Bio cloned five puppies from customer Bernann McKinney's pitbull terrier, Booger. McKinney says she was especially attached to Booger since he fought off another dog that attacked her and then became her service dog as she healed. Lee was involved in the cloning of Snuppy in 2005. The puppies were born July 28th and are called Booger Bernann, Booger Ra, Booger Lee, Booger Hong, and Booger Park.
