Poola Bopper had a different surname (long forgotten to her) when she was assigned the title of "Bopper" by Clang Zoop, the leader of the Gully Dwarves. She adopted Bopper as her official name as well as her title. She was assigned to protect Bokk, and during the time that she was assigned to watch over Bokk, she actually fell in love with her (and he with her). She's told him that she will be second queen (once Bokk proposes to her).
