Physical Appearance
In Super Mario World, Yellow Yoshi, like the other Yoshis in that game, had yellow skin, but orange gloves, brown shoes, and a brown saddle.

In Super Mario World 2: Yoshi's Island, Yellow Yoshi looked about the same as it did in Super Mario World, but with orange shoes and an orange saddle (as well as orange arms). However, in the Game Boy Advance port (and following games), Yellow Yoshi wore light green shoes.

From Yoshi's Story and beyond, Yellow Yoshi had light green shoes and a red saddle.

Personality
In the games Super Mario World 2: Yoshi's Island and Yoshi's Island DS, Yellow Yoshi is a brave hero that helps Baby Mario rescue Baby Luigi from Kamek's clutches. Additionally, the Yellow Yoshi, along with Baby Donkey Kong, joined the other Yoshis and infant heroes to defeat an enlarged Bowser.

When not battling enemies or bosses, Yellow Yoshi enjoys eating, of course, and taking naps. In fact, it is implied that all members of the Yellow Yoshi race may share the inherent trait of extensive hunger and adjacent slothfulness. The yellow member of the Fearsome 5 in Paper Mario had a food obsession, focusing on Jade Jungle's fruit during his forbidden journey there, and another Yellow Yoshi on Lavalava Island will give Mario a melon in return for food made by the famous Tayce T. of Toad Town. The Yellow Yoshi of Mario & Luigi: Partners in Time also loved eating, and was always complaining about hunger and even occasionally refusing to move on without food.
