"Jumanji Jumanji" is presented as an alternative theme song for the movie Jumanji: Welcome to the Jungle, performed by Jack Black and Nick Jonas. The music video features a humorous clip of the movie's cast-including Dwayne "The Rock" Johnson, Kevin Hart, and Karen Gillan-joining Jack and Nick to evaluate their song.
Obviously, Jumanji Jumanji isn't a serious competitor to the Guns N' Roses classic. While the Jumanji cast may not fully approve of it, the song is actually quite fun and perfectly embodies Jack Black's signature comedic style. This is evident not only in the song's playful nature but also in the intentionally low-budget quality of the video.
