Perona's Terror!! The U in Uso is the U in Usopp

The battle between Usopp and Perona continues; Usopp fires something at Perona's real body which seems to miss it, giving Perona the confidence to fight back again. This time she produces a huge hollow, at least four times the size of Usopp, which grabs Usopp in its mouth and won't let go, leaving Perona time to go and return to her body. She detonates it, but the explosion gets sucked into the impact Dial, which Usopp cleverly brought out. He uses this on a Zombie-Hippo which was sneaking up, breaking his arm, but he then reveals that he stuck Perona's arm to the wall; he wins the battle by firing hundreds of little moving fake cockroaches onto her, and then smacking her over the head with an inflatable ten-ton hammer.
