Yoshi

While Mario, Goombella, Koops and Flurrie are fighting in Glitzville's Glitz Pit, they find that one of the fighting teams, the Armored Harriers, seem to be impervious to any attack they use. At an earlier time, Mario had found a Yoshi Egg bouncing around, being chased by the owner of the Hot Dog Stand, Mr. Hoggle (who had hopes of making a Southern Fried Egg Dog of Tastiness with it). Mario eventually caught it, and Mr. Hoggle allowed him to keep it as most people "don't like to eat things that move". After Mario returns from his problematic battle with the Armored Harriers, the egg hatches into a Yoshi kid who thanks Mario. He then joins Mario (who he knows as Gonzales), who proceeds to name him. The Yoshi Kid can defeat the Armored Harriers by eating them and spitting them at each other. He travels with Mario for the rest of the game.
