Ostro

Ostro was the name of the ostriches Shy Guys rode in Super Mario Bros. 2. It is famous for being half the precurser to Yoshi(The other half belonging to Birdo.), and, ironically, being credited as Birdo in the credits of Super Mario Bros. 2. This like many other mistakes is fixed in later versions of the game. Although an obscure character who probably wouldnt even of been noticed if not for the credit mistake, there are some fans who want them to make a return.
