"Invincible Candy" is a typically swift and upbeat theme in F major and 4/4. In most variations of "Invincible Candy", the high tempo and swift beat are used to convey the speed and power granted by the Invincible Candy. The theme consists of two short phrases: one consists of a short a simple motif of three rising notes and a falling sixth played twice, while the second is a virtuosic descending passage ending in a rising octave.
The first motif follows a chord progression of IV-I-VII-I, the chord changing every two beats; the VII chord, E flat major, substitutes the vii chord, E diminished, that normally appears in the key of F major. The second motif follows a simple IV-VII progression, the chord changing every four beats. By using all major chords and lacking the dominant V, the theme has a hyperactive energy that doesn't quite resolve, adding to the feeling of a sugar rush.
Most titles simply loop their version of the original melody with no variation, although starting inKirby's Return to Dream Land, some notes in the theme are altered when the melody repeats, making the loop slightly longer. This practice comes to a head inKirby and the Forgotten Land, where the song doesn't loop until after four variants have played.
Two new arrangements appear inKirby Super Star and itsremake respectively. In addition to playing when consuming Invincible Candy, the theme also appears if obtaining "Super"/"Invincible Candy" in themix roulette. It can be found in theSound Test as track 57 in the original and track 68 in the remake.
InKirby's Dream Land 3, another arrangement of the theme plays under the same circumstances as a majority of the titles, also appearing in theSound Test as track 32. This version of the theme has detached brass notes.
InKirby Tilt 'n' Tumble, a smoother arrangement plays once again after the consumption of Invincible Candy, and can be found in theSound Room as track 14.
Despite not appearing fully inKirby: Canvas Curse, a new iteration of the first phrase of "Invincible Candy" is a part of the credits theme together with "Gourmet Race", which also appears in theSound Test as track 44.
InKirby: Squeak Squad, a new arrangement based on theKirby: Nightmare in Dream Land version plays when consuming Invincible Candy from the food source or abubble. It appears as track 09 in theSound Room after collecting theHappy Notes.
Kirby's Return to Dream Land /Kirby's Return to Dream Land Deluxe[edit]
InKirby's Return to Dream Land and itsremake, a somewhat extended arrangement similar toKirby: Squeak Squad's version appears. Notably, this is the fastest version of "Invincible Candy". It appears in the original'sSound Test as track 14 and in the remake's Jukebox as track 15, and was arranged by Jun Ishikawa.
InKirby: Triple Deluxe, two versions of the theme appear simultaneously: a new slower arrangement for Story Mode andDededetour (simply titled "Invincible", arranged byHirokazu Ando[6]), and the version fromKirby's Return to Dream Land forKirby Fighters. They appear in theJukebox as track 13 and 50, respectively.
InKirby and the Rainbow Curse, an acoustic arrangement (titled "Invincible!") appears. This is the slowest of the versions of "Invincible Candy". In theMusic Room, it can be found as track 49 after defeatingWhispy Woods inGreen Valley for the first time.
InKirby Star Allies, a new arrangement (most closely resembling theKirby Super Star version) plays, and can be found in theJukebox as track 12. This arrangement was done by Jun Ishikawa.
InKirby's Dream Buffet, a unique arrangement based on exclusively the second phrase of "Invincible Candy" plays for the player that uses the Invincible Candy. Unlike in other games, it is internally considered a sound effect instead of a music track.
