Birdo 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 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.
My son who is 22 with Autism absolutely love her! My husband also couldn’t stop taking about how adorable Birdo is. Highly recommend for anyone who loves Yoshi!
