''Super Mario Advance
In Super Mario Advance, Robirdo was created by Wart and is a new boss of the 8 Bits. It helped Wart and the generals conquering Subcon.

Robirdo has three attacks in battle: The first attack is a classic Birdo attack - firing eggs from its mouth. This is immediately followed by its second attack, which is charging directly towards the player. The seven chains hanging from the ceiling assist the player to avoid this attack. The third attack is used once Robirdo has been damaged - a Ground Pound-like attack that immobilizes and damages the player. The charge also follows the third attack. The only way to damage this boss is to throw the giant eggs, which it shoots from its mouth, back at it. It takes five hits to defeat this boss.

Trivia
