From the Super Mario Wiki
Eggberts are enemies found in Super Mario RPG: Legend of the Seven Stars. They are occasionally spat out by Birdo, in place of normal Birdo Eggs. Eggberts explode on contact and can be deflected by defending. Once an Eggbert is deflected, it can be attacked. If an Eggbert is defeated, it explodes and causes heavy damage to Birdo. They simply run into a character and explode if left unharmed. Eggberts have high attack power, but can be defeated by the weakest of attacks.
