スーパーマリオコレクション
Birdo is a pink, anthropomorphic creature who wears a red hairbow, and has a round mouth that can fire eggs as projectiles. Birdo also wears a large diamond ring. In the early version of Birdo, the character had an orange tone. Birdo's name was mistakenly switched with another "Super Mario Bros. 2" enemy, Ostro, both in the manual and in the end credits. The mistake persisted in the version of "Super Mario Bros. 2" included in the "Super Mario All-Stars" compilation, but was corrected in the Game Boy Advance re-release titled "Super Mario Advance".
