Monkey D. Luffy is the rubber powered captain from Eiichiro Oda's One Piece, which began as a manga in 1997 and became a long running anime in 1999. Forro is a popular music and dance tradition from northeastern Brazil, built around accordion, zabumba and triangle. Online editors combine the two because Luffy's carefree personality fits the music's festive mood, and short mashups like this circulate easily as reaction audio on social platforms and soundboards.
