Trivia

 * This map has a glitch where thugs tend to get thrown highly up in very high speed upon being attacked, which works as a detriment as they fall and get incapacitated making the player lose on score that they would gain from battling these thugs.
 * One thug on Expert Round 2 is a Penguin's Henchman without a rabbit mask.
