Super Mario Advance/Robirdo

Robirdo is a boss in Super Mario Advance. It is a giant, robotic version of Birdo. The fight against Robirdo replaced a Mouser battle that was in Super Mario Bros. 2.

Robirdo jumps, shaking the ground and stunning Mario, Luigi, Princess Peach, or Toad if they are on the ground. Then, it runs forward. Another attack is spitting two giant eggs. All three of these attacks can be evaded by climbing the chains that hang down in the room.

Robirdo can be defeated by throwing eggs back at it.
