The Yellow Egg is a type of Yoshi Egg that would first appear in Super Mario World. When the player draws close to the egg in Super Mario World, it will hatch into a Baby Yellow Yoshi. The Yellow Egg would play a more important role in Super Mario World 2: Yoshi's Island. When a Green Egg recoils off a wall, it will turn into a Yellow Egg. The Yellow Egg could also be found in yellow Egg Blocks.
