well yoshi in my real life mario serie is a evolve raptor specie to be eating vegetables just like meat.so that makes them more tend to be umble dino.mario gets to see the yoshisaurus when the wild toads tells about how they formed a suport beetween them and the yoshis, yoshis give them protection and traveling help and in return the mushroom ppl give them better habitats construction ect.so your new friend toad brings you to the nest of the yoshisaurus and tells you to bund with one.the way is to see what yoshi will chalenge you to death O.O so there cam this young male yoshisaurus... after the challenge he desides to make you a friend sins the yoshisaurus are very inteligent dinos and saw great warrior of hope in you so you deside to name him simply Yoshi ^^ trew out the game yoshi will be more then a simple friend and do way more then just be a riding dino ^^ the yoshisaurus are not a specie affected by the mutation its a natural evolution and they shure do not bowe to king koopa bowser.they have beautifull red hair like horses its a evolution ater behing herbivorus as well then carnevorus of course there toung is still long and is a great way of defents and attacking.
