Welcome To Yoshi's Island

Welcome to Yoshi's Island is a one-time playable level in Super Mario World 2: Yoshi's Island and it's remake, Super Mario Advance 3: Yoshi's Island. It can only be played when a new game is started. It is mainly a tutorial in which Yoshi learns about Baby Mario, as well as using Expand Blocks and collecting coins. The level is incredibly basic and short, with only few Shy Guy enemies strolling around. As this mini-level ends, Yoshi begins level 1-1, Make Eggs, Throw Eggs.
