 The inspiration for Yoshi can be traced back even further; Miyamoto designed a green dragon for the 1984 game "Devil World" which shared many similarities with Yoshi.During the development of "Super Mario Bros. 3", Miyamoto had a number of sketches around his desk, including an image of Mario riding a horse.As development of "Super Mario World" progressed, the team opted to set the game in a "dinosaur land", so Tezuka asked designer Shigefumi Hino to draw a reptile-like creature based on Miyamoto's sketches.
