Yoshi (ヨッシー, Yosshī, [jo.ɕːiː]) (English: /ˈjoʊʃi/ or /ˈjɒʃi/), once romanized as Yossy, is a fictional anthropomorphic dinosaur (referred to as a dragon at times) who appears in video games published by Nintendo. Yoshi debuted in Super Mario World (1990) on the Super Nintendo Entertainment System as Mario and Luigi's sidekick (a role often reprised by Yoshi), and later starred in platform and puzzle games, including Super Mario World 2: Yoshi's Island and Yoshi's Story.
