Birdo

Beta Birdo (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 Yoshi 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. The reason for this color pink is for contrast Yoshi's color. She also is a good friend of Daisy, Toadette, and Petey Piranha. Other Birdo characters have resided in Subcon, in Nimbus Land, and in other locales.

In Super Smash Flash 2
Birdo appeared in Super Smash Flash 2 as a stage hazard in the demo v0.6 and v0.7 in the stage Mushroom Kingdom II, before that stage got removed in favour of Mushroom Kingdom III. As she did in Super Smash Bros. Melee, she walked out from the edges of the stage shooting eggs in a straight line from her snout. These egg damage players on their path.
