Zombie Night

Zomibe Night is a song the zombies of Thriller Bark sing during the Thriller Bark arc. When the zombies are ordered to commence the attack on the Straw Hat Pirates, they perform a little disco ball aided dance reminiscent of Micheal Jackson's Thriller. While the manga's depiction of the dance was just a single panel and the song the zombies sang was just a few lines, the dance was expanded in anime. In the anime, it is a full blown dance number called zombie night where the zombies danced and sang to a tune reminiscent of 70's disco music.
