Yoshi's Egg is a special item that only appears in Event 13: Yoshi's Egg. This Yoshi's Egg should not be confused with Yoshi's Up B move or Side B.

Yoshi's Egg can be picked up and tossed around, however, the egg is not meant to be used as a weapon--players are supposed to protect it as Yoshi. The egg will break after it drops or is thrown constantly. If the egg is broken, players then lose the Event match. Nevertheless, it still functions as a throwing weapon, doing 17% damage. The damage is not increased by smashing.
