You may or may not know that Chibi-Robo went through many different varitations during it lenghty development time. The game was originally intended to be more like a ‘point-and-click’ and the story was about Chibi rescuing his creator from a group of burglars. That is until Shigeru Miyamoto stepped in and helped skip re-design Chibi-Robo into the semi-platform game we know and love.
I’ve known this for a while but it was only recently that I discovered a couple of You-Tube videos that show exactly what Chibi-Robo looked like early on in production. Here they are for your amusement/enlightenment.
