: The episode ends with the grand opening of the Devil's Casino , a major location from the original Cuphead game, which Cuphead immediately runs toward despite warnings.
The original title was likely referencing the 1989 Batman film.
: After the Devil technically wins the dance battle, Cuphead intervenes by challenging him to Rock, Paper, Scissors . Cuphead miraculously wins five rounds in a row to save their souls.
: The background music during the dance battle shifts between variations of "The Devil's Song" and "Sail Across a Rainbow" (Chalice’s theme), depending on who is winning. The rhythm also draws inspiration from the 1936 classic "Sing Sing Sing" by Louis Prima. Cultural References :
