Yoshi’s signature egg item in Mario Kart: Double Dash!! is green. The egg is Yoshi’s exclusive special item, shared with Birdo, and it rolls forward before breaking to release several ordinary items.
The item reflects Yoshi’s familiar visual identity: the character is traditionally green, and his standard eggs are also shown with green-spotted shells. In Double Dash!!, the egg is larger and more distinctive than a normal item capsule, making it easy to recognize during a race.
The egg can produce useful or disruptive items, including bananas, green shells, Bob-ombs, and, in some circumstances, other objects. Because the contents are not fixed, collecting a Yoshi Egg does not guarantee one particular power-up.
Players sometimes confuse the green egg with Yoshi’s alternate colors or with the colored eggs seen in other Mario games. Double Dash!! also gives each character pair a special item: for example, Mario and Luigi use the Fireballs, while Bowser and Bowser Jr. use the Bowser Shell. Yoshi and Birdo are the pair associated with the egg.
