Kirby & the Rainbow Curse has an Unused Waddle Dee

[CuriousUserX90]

Here's a gameplay video of all 3 Waddle Dees (Red, Yellow and Green) that players with Wii Remotes can assist you with in the game, but in the game's promotional art from E3 2014, it appears that there was to be a 4th Waddle Dee as well, of which wasn't seen in the Final Game, as seen in this screenshot.:

Not much Wii U games have used 5 Players throughout the years, not even this game and SM3DW, namely just it's launch games and Mario Party 10. This unused Waddle Dee is Cyan Coloured FYI.
