Tightrope Walking Funan Bros

The Tightrope Walking Funan Bros (綱渡りフナンボローズ) are a trio of minor pirates in the Buggy Pirates.

History
They tricked by Nami and later found at sea by Roronoa Zoro. After they are picked up by Zoro, they tried to take over his boat and end up getting beaten for their efforts.

At the end of the Buggy arc, they are revealed to still be in the boat (which was anchored by the coast the entire time), and upon seeing Nami, attempt to attack her... until Zoro reveals his face, at which point they flee.

Afterwards, they return to Buggy's ship, helping him find the Straw Hats and One Piece.
