Yoshi

Introduction
Yoshi is a Yoshi. With this said, we can conclude. And infer. That Yoshi belongs to the Yoshi species, was hatched on Yoshi's Island and is named Yoshi. Just like every preceding and forthcoming member of Yoshikind. Oh well...

Yoshi is a wannabe. That pretty much sums up his character.

Here's a convenient list of all of Yoshi's endeavors which are worth highlighting.
 * Being tossed into pitfalls
 * Eating a quantity of berries so absurdly huge that could solve Earthling famine
 * Stealing Mario's wallet
 * Dating Birdo
 * Being a complete asshole
 * Setting up deadly bear traps for kids on Halloween
