Tightrope Walking Funan Bros is the name of the tightrope walking troupe from Buggy’s gang. They wanted to steal Nami’s gold, who was playing the weakened one. But instead, Nami took over the boat they arrived on. The three were therefore on Nami’s small boat when it sank in a storm shortly afterwards.
Later they boarded with Zoro, who was rowing after Luffy, who in turn had his head in Pinky’s beak. When they tried to take over his boat, he taught them a lesson and made them row for him from then on.
