The Yoshis are a recurring species in the Mario series. They are bipedal, reptilian, creatures who inhabit the Mushroom World. They originate from Yoshi's Island and appear to have a very intricate society. Most of the Yoshis inhabit Yoshi's Island or other tropical islands found in the Mario Universe. Green Yoshi appears in Mario games more often than other Yoshis. They are a reference to dinosaurs, as shown in Trivia.
Para Yoshi is also Yoshi's final smash in Super Smash Bros. Brawl
As previously mentioned, Yoshis are bipedal, tailed reptiles that inhabit the Mushroom Kingdom. All Yoshis have saddles given to them at birth as well as nice shoes that also were obtained at birth. While all very similar in appearance, Yoshis do vary in colors. Yoshis are known to appear in several different colors:
Green Para Yoshi (Red) (Only in Super Smash Bros. Brawl)
The color of the shoes of Yoshis changes depending on the color (the color in brackets is the color of the shoes of the various Yoshis).
Powers and abilities
One of the Yoshis' key abilities is to grab enemies with their tongues. From there, they can transform enemies in their mouths into eggs, and throw the eggs, or they could spit the enemy back out. Another ability is the Flutter Jump which allows them to gain extra height after a jump. Yoshis are also able to do Ground Pounds. They are also able to transform into different vehicles. In Super Mario Sunshine, they can change color depending on which fruit they eat and can squirt juice from said fruit from their mouths. However, they cannot stand water, as they dissolve the moment they touch it. In Super Mario Galaxy 2, they can use their tongues as grappling hooks; this is similar to one of the things they could do in Yoshi's Story. The Para Yoshi can fly. Para Yoshi is only seen in Super Smash Bros. Brawl as Yoshi's final smash. Para Yoshis can also shoot fireballs out of their mouths just like after eating a Red Koopa Shell.
Although some Yoshis can speak the language of most citizens of the Mushroom Kingdom, the Yoshis have developed their own language of sorts. In older games, like in Super Mario World the Yoshis' only "voice" was an odd sound created by a reversed record scratching sound effect. In later games, the language consists of numerous exclamations and unintelligible noises. Oddly, most Mushroom Kingdom characters are able to understand the Yoshi language.
Like Yoshi, the other Yoshis are capable of racing as they are seen as racers in Mario Kart 8. They can be unlocked as long as you already bought the Link and Animal Crossing (separate or bundle) DLC.
Trivia
Yoshis are similar to dinosaurs and other real life creatures. Additionally, Yoshi has an alternative name "Yoshisaurus", which is a reference to dinosaurs, as a lot of them has the affix "saurus".
The Yoshis have also inhabited Isle Delfino as mentioned by a Toad.
Yoshis were originally going to be a special type of Koopa Troopa. This was scrapped in favor of Yoshis being made into a dinosaur-type creature.
Yoshis were possibly based on an early game Miyamoto made called "Devil World."
