Birdo

Birdo (Japanese: キャサリン Kyasarin) is a recurring character in the Mario series. In fact, there have been multiple characters known as "Birdo," similar to the multiple Yoshis that have appeared throughout history. The concept of a Birdo character was not solidified until the same pink Birdo began appearing in various spin-off titles. The central Birdo character (that appears in the Mario Kart series, the Mario Party series and the various sports titles) wears a red bow and a diamond ring. She also has some sort of relationship with Yoshi, as they are the automatic partners in various competitions. She is a good friend of Daisy, Toadette, and Petey Piranha. Other Birdo characters have resided in Subcon, in Nimbus Land, and other locales. - From the Super Mario Wiki
