— Fan Club Description (Rhythm Heaven Megamix)
Template:Game-NavTemplate:Game-NavTemplate:Minigame infoboxFan Club (アイドル?, Idol) is the 4th minigame in Rhythm Heaven and the 49th minigame in Rhythm Heaven Megamix. This game is about a Pop Singer performing the song "Thrilling! Is This Love?" while being cheered on by monkeys. The sequel, Fan Club 2, is unlocked later on.
Pop Singer stands in the center of the stage performing while her monkey fan club cheers her on. The player takes control of the monkey on the far right of the front row. Certain phrases in Pop Singer's song indicate what action the player must take. When she sings "Yeah, yeah, yeah!" (ハイ!ハイ!ハイ!?, Hai hai hai!) or any other phrase repeated three times, the fans are expected to clap four times directly afterward. The other duty of her fanbase is to clap three times and then follow with a short jump after she recites the line "I suppose" (かもね!?, Ka mo ne!). The audience echoes her, but stretches out the "I" and adds in a "hey!" when they hop. For each syllable repeated by the monkeys, a clap is performed. In Rhythm Heaven Megamix, the game's appearance was drastically changed, taking place inside on a stage rather than outside. The player now controls the middle-right monkey in the front row.
Unlike Fan Club 2, clapping at the end of the song will count as a miss.
Pop Singer's design in Rhythm Heaven resembles a singer known as Erina, who also voiced the character in the Japanese version of the game. Her new design in Rhythm Heaven Megamix resembles another singer known as Ari~sa, who revoiced the character in the Japanese version after Erina had left Canary Club in 2009.
Soushi Tanaka, who looks like the Student Guitarist from Rockers, makes a cameo in Try Again epilogue in Rhythm Heaven Megamix.
