In Teenage Mutant Ninja Turtles II: The Secret of the Ooze, Vanilla Ice performs “Ninja Rap.”
The song appears during the film’s climactic confrontation at a nightclub, where the Turtles battle the Foot Clan. Vanilla Ice’s performance became one of the movie’s most recognizable scenes and helped connect the film to early-1990s hip-hop culture.
The song is sometimes remembered by the lyric “Go ninja, go ninja, go,” which has led some people to give that phrase as its title. “Go Ninja Go” is also used as an alternate shorthand in popular discussion, but the official song title is “Ninja Rap.”
The film was released in 1991 as the sequel to the 1990 live-action Teenage Mutant Ninja Turtles movie. Its plot centers on the Turtles’ origins and the mutagenic ooze that transformed them.
