Yoshi is very brash and adventurous. He is known to make witty yet ironic remarks about people, places, and things.
He can do what a normal Yoshi can. However, unlike normal Yoshis, Yoshi is able to use power-ups, like what Mario and other various people in the Mushroom Kingdom are able to do.
He used to live on Yoshi's Island, but soon afterwards, he moved over to the Mushroom Kingdom. Soon after a major argument with his parents, he got fed up and moved out. A few weeks later, after a few failures on building a house for himself, he met Boo and Paratroopa as they were running from Bowser's forces. After they defeated Bowser's forces together, they decided to become a trio of best friends.
Prior to the first episode, Yoshi asks Paratroopa to bring something for entertainment.
He, along with Paratroopa, go off to Dreamland to find Boo and compete in a singing competition. In Chapter 8, he loses his memory for a brief period of time. During that time, he called himself the "Splendid Bird from Paradise" until Marx dunked his head into a waterfall.
