Police Call/Unused

Rhythm Heaven Fever
Police Call consists of the following versions in Rhythm Heaven Fever:

Unused Content
There are unused sprites of various characters meant to replace the young man in Police Call. These include an older man, a woman, and a robot. In addition, there are also two more characters along the top hat-wearing person; one is a boy in glasses and a baseball cap, the other is a skinny man in a scaly cap.

There is one piece of dialogue intended for Police Call which goes unused. It is blank in Rhythm Heaven Fever, but translated in Beat the Beat: Rhythm Paradise:

Regional Differences
The layout of the keys is different in Minna no Rhythm Tengoku, displaying various hiragana characters as opposed to the latin alphabet. The envelope used to represent sending the code word also has a heart-shaped seal, which is not present in other versions.

The character's mouth is intended to open and close rapidly as the text is displayed. While it does so in Minna no Rhythm Tengoku, the speed at which the text is displayed is doubled in other versions, causing the animation to loop more quickly. The animation was not adjusted for this change, and as a result the character's mouth remains open for a longer period of time.
