Birdo is a medium-weight character who rides medium bikes and karts.
Birdo lives in the Mushroom Kingdom. She's a medium weight character. She debuted in Super Mario Bros. 2, as a boss; she spat eggs out of her mouth at the character. Since then, she's taken on more friendly roles in spin-off games, even having some romantic ties with Yoshi. There is a theory that she is a male. She was the first transsexual video game character ever. Birds are probably a sub-species of Yoshis. They come in different colors. In some games she has a normal voice, but she mostly makes roaring sounds.
- Her boyfriend is Yoshi.
