Kung Fu Ball/Unused

Rhythm Heaven Fever
Kung Fu Ball consists of the following versions in Rhythm Heaven Fever:

Unused Content
There are unused sprites in Kung Fu Ball of a yellow, blue and red ball, as opposed to the bronze, silver and gold ones used in the final game. There is also a sprite of a dragon drawing. There are sprites of an early design for the kappa, as well as an old man holding a staff riding a cloud.

What appears to be two sets of early dialogue for Kung Fu Ball can be found in Minna no Rhythm Tengoku. In Rhythm Heaven Fever, these lines are blanked. These lines imply that the Great Bird Claw Spike would've involded the students transforming into dragons. In Beat the Beat: Rhythm Paradise, they are each replaced with the respective language (written in English) and in Rhythm Sesang Wii, they are replaced with 미사용 (Unused).

The first set doesn't use the special icons for the Ⓐ and Ⓑ buttons, and doesn't have the "kapa" at the end of each sentence. The second set uses the special icons for Ⓐ and Ⓑ and ends the sentences with "kapa", as in the final game.
