Nintendo had wanted Mario to have a dinosaur companion ever since the first release of "Super Mario Bros."; however, it was not possible because of the limitations of the NES. The inspiration for Yoshi can be traced back further, to the green dragon Tamagon in the 1984 video game "Devil World:" both are green lizards that hatch from eggs and can eat enemies with their large mouth, and also emit the same noise when they hatch. During the development of "Super Mario Bros. 3", Shigeru Miyamoto had a number of sketches around his desk, including an image of Mario riding a horse. Takashi Tezuka, a "Mario" series developer, speculated that Miyamoto's love of horse riding as well as country and western themes influenced Yoshi's creation. The concept of Mario riding a dinosaur also came from the NES video game "Excitebike", which featured people riding motorcycles. He again wanted to feature Yoshi in "Super Mario Bros. 3", but was still unable to. Tezuka designed two power-ups (the frog suit and raccoon tail) to make up for this limitation.
