8. The pink blob was a placeholder
In an interview with Masahiro Sakurai, it was revealed that Kirby's design was originally just a placeholder created during the development of Kirby's Dream Land. This explains Kirby's very simple, blob-like appearance. Over time, Sakurai grew fond of the placeholder and felt it worked better than later designs, so decided to stick with it. Kirby was also known as Twinkle Popopo during this time.
