Each Super Mario Mini Figures Two-Packs figure is a fixed-pose figure with a translucent red base.
A Blue Yoshi typically has a red shell/saddle and red shoes, and he can fly so long as he holds a shell of any color in his mouth. If a Yoshi becomes a Blue Yoshi by virtue of the Wing Power-Up, he and Mario are corralled into a temporary bonus stage.
A Pink Yoshi will sometimes have a red shell/saddle and yellow shoes. In New Super Mario Bros. Wii, the Pink Yoshi is rideable, replacing the originally intended Red Yoshi.
