Fan Club/Unused

Rhythm Heaven
Fan Club consists of the following versions in Rhythm Heaven:

Unused Content
There are unused sprites of the Pop Singer blinking as well as one of her almost falling over, the latter being similar to the animation of the Girl when shes misses the jump cue from Tap Trial. All of these sprites appear in multiple variations, all of which show the Pop Singer doing those actions in her different outfits from nearly all versions of the Rhythm Game, although it lacks ones for her Remix 7 outfit. There's also larger versions of some of these sprites, presumably intended for the big screen seen in the background of Fan Club 2.

Various unused sprites of the Monkeys doing some actions also exist, such as one of them scratching their heads, waving their arms to the side, as well as an early version of the animation of them glaring at the player. Like with the ones of the Pop Singer mentioned earlier, these sprites all come in multiple variations for each of the different versions of the Rhythm Game.

Rhythm Heaven Megamix
Fan Club consists of the following versions in Rhythm Heaven Megamix:

Unused Content
There are unused sprites of a microphone and a ponytail from the Pop Singer's original design seen in Rhythm Heaven, specifically in her Fan Club 2 attire.

There's also an unused expression of the Pop Singer, this time in her current design, with her eyes closed and a distressed look on her face.
