Camel

Camel is a pink camel with a large neck that replaced the Giraffe in the minigame Tap Trial 2 in Rhythm Tengoku, but it did never make an appearance in the game at all which goes as an unused character.

Trivia

 * The camel's sprites can be found in the files in Tengoku's ROM. Interestingly, its sprites were redrawn in Megamix but they also go unused there.
 * Strangely, the camel can be seen in the title screen of Tap Trial 2 in Megamix, though.
