Mr. Batty Twist is a song in Mother 3. The tune plays only when the player encounters a Mr. Batty as the name would suggest. It's mostly rock, and has a fast rhythm that's not too hard to catch on. It's one of the few regular enemy songs that doesn't have a "hard" variant.
- The start of this song sounds almost identical to the opening theme song of the 1960s Adam West Batman television show.
- Excluding the intro, all of the song is used as part of the Porky's Porkies song later in the game.
- Midway through the song, the melody becomes Theme from Phantom of the Opera.
