List of Super Mario World 2: Yoshi's Island pre-release and unused content

This is a list of pre-release and unused content for the game Super Mario World 2: Yoshi's Island.

Early iteration
Nintendo marketing department initially pressured Shigeru Miyamoto to have the game use prerendered 3D sprites similar to Donkey Kong Country. The 3D models of Baby Mario and Yoshi used in the introduction might be leftovers of this period of development.

Early concepts

 * The developers experimented with several concepts before settling with the final idea of "a game where even though you hit enemies, you don’t die.". One of them was to have Yoshi move independently from Baby Mario and guide him around the levels.
 * The Superstar Baby Mario form was initially supposed to an adult, bearded Mario but it was pointed out this concept would seem strange. Shigeru Miyamoto joked he still prefers this early idea to the final version.
