Who's the Real One!.Chacha and friends are entering the dungeon, and Haideyansu and Yordas are convincing the resident mimic monster, Modoking, to stop Chacha. Chacha and her friends stumble across Yakko, who is looking for rare herbs only found in that dungeon. Chacha sees a mouse and run off down the passage, setting off a trap that traps her behind the wall. While Riiya is breaking down the walls that keep popping up, Shiine tries some magic but bumps another trap which puts him behind another wall where he steps on one of the mimics sent out by Modoking. Another mimic tricks Riiya into stepping on it in order to duplicate him as well...
