Yoshi's Island (location)

Yoshi's Island is where the Yoshis were first discovered (and appear to be native to), hence its name. The island is part of a larger land called Dinosaur Land and first appeared in Super Mario World.

Super Mario World
In Super Mario World, it was the first world of the game. Yoshi's House is located on the island as well as the Yellow Switch Palace and Iggy's Castle. After the castle is cleared, a bridge opens to the Donut Plains. The world was grassland-themed.

The world contains the following levels:
 * Yoshi's House
 * Yoshi's Island 1
 * Yellow Switch Palace
 * Yoshi's Island 2
 * Yoshi's Island 3
 * Yoshi's Island 4
 * #1 Iggy's Castle

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, it goes by the name Yo'ster Isle. It is an optional area and can be easily bypassed by ignoring the Pipe Vault and moving on to Moleville. The island is the home to many Yoshis of various colors. Yoshis find entertainment in the Mushroom Derby, a short race on the island's track. The Yo'ster Isle Yoshis enjoy racing and hold the Derby often. The island is also a famous tourist destination; for many years, people from around the world have traveled to Yo'ster Isle to experience its many features.

Yo'ster Isle is connected to the mainland by a Warp Pipe to Pipe Vault. The island is rich with vegetation and scattered with trees. No true buildings exist, yet small, open shelters made of wooden poles and covered with leafy roofs provide the Yoshis with protection from harsh weather. Most of the Yoshis can't actually speak directly to humans; only Yoshi can communicate with Mario, and acts as translator when talking to the others. Besides Yoshi himself, there are several important Yoshis: Boshi, a blue Yoshi known for his antisocial behavior, and a small, green, Baby Yoshi that hatches and grows during the course of the game, though never leaves the small nest. If Mario feeds him enough cookies, he will eventually be rewarded with a few rare items, including Red Essence.

Boshi was once considered the leader of the island after he won the Mushroom Derby and declared himself boss of the Yoshis. However, with the help of Mario and Yoshi, Boshi was defeated in another Mushroom Derby race and the Yoshis began to live freely again. Although the Yoshis make up the indigenous population, the island is considered a vacation hotspot and Raz and Raini, two Toads from the Mushroom Kingdom, spent their honeymoon there.

According to the Super Mario RPG: Legend of the Seven Stars Player's Guide, Yo'ster Isle is a part of World 2: Pond to Pipes. However, on the in-game map screen, the level is accessed as if it belongs to its own world connected to but distinct from World 2.

Paper Mario
In Paper Mario, the Island was known as Lavalava Island. It is debated whether the two islands are the same place or not, but in Paper Mario it was stated that Lavalava island was the only place where Yoshis lived, and the game Yoshi's Island the same was said about the titular island.

Mario Golf
Yoshi's Island is also one of the courses in Mario Golf for the Nintendo 64. It can have winds of up to 20 miles per hour and the occasional rain that slows down shots. It is mainly bumpy and has holes in which players need to shoot over the water to avoid an O.B. water hazard penalty. As players approach the latter holes, the day turns to sunset. Strangely, constant Donkey Kong voices are part of the ambiance.

Mario & Luigi: Partners in Time
During the events of Mario & Luigi: Partners in Time, Yoob and the Shroobs attacked the island. Mario, Luigi, Baby Mario and Baby Luigi saved this island. This game portrays the island with unique enemies such as Pidgits who were only known to exist in Subcon and Coconutters who are a completely new species. There were Yoshi statues around the island, and one of them had a hole where the spring water was coming out. Baby Mario must drink some of this water to get full of water, and then make Baby Luigi hammer him and then Baby Mario will spit the water out. This move is useful to douse bonfires.

Mario and the Incredible Rescue
In Mario and the Incredible Rescue, Yoshi's Island once again appears, again by the name Yo'ster Isle. During the adventure, Mario, Luigi and Toad traveled to Yo'ster Isle looking for the next Mushroom. They end up getting attacked by Lakitu and Spinies, but Yoshi arrives and eats Lakitu's Cloud. As such, Mario can get the Mushroom and escape, allowing his party to advance to Moleville.

Super Mario World 2: Yoshi's Island
It next appeared in Super Mario World 2: Yoshi's Island, when Baby Mario fell down to the island after the Stork carrying the Mario brothers was attacked by Kamek. Yoshi found lost Baby Mario, and the Yoshis decide to team up and rescue Baby Luigi and send the Stork on its way. Only enemies, minibosses, and bosses stand in the heroes’ way.

Yoshi's Story
In Yoshi's Story, Baby Bowser took over the island in an attempt to capture the Super Happy Tree. Bowser placed a spell over all the Yoshis, but six were unaffected (as well as two more later on), as they were unhatched and still in their eggs at the time the spell was cast. The six Yoshis must battle their way to Baby Bowser while eating fruit and regain their island by defeating Baby Bowser and breaking the spell and got the island back.

Yoshi's Universal Gravitation
Similar to Yoshi's Story, in Yoshi's Universal Gravitation, the island is locked inside a pop-up book, this time known as the Forbidden Pop-Up Book. A spirit, named Hongo, felt threatened by Bowser and tried to lock him away in the book. The book was too powerful and sucked in all of Yoshi's Island, turning everything into paper. Yoshi, assisted by the Yoshi Island Spirits has to traverse the Island to reach Bowser. If he can defeat Bowser, Hongo will return the island to its normal state.

Yoshi's Island DS
The island reappeared in Yoshi's Island DS, where many babies ended up here. Kamek starts to kidnap babies from all over the world, including Baby Mario, Baby Luigi, and Baby Peach. Luckily, the Stork arrives just in time to rescue Baby Mario and Baby Peach. The Yoshi clan end up finding the babies again, and decide to help Baby Mario rescue his captive brother, and the rest of the kidnapped babies. Yoshi ends up finding two other captured babies, Baby DK and Baby Wario, who decide to help find the babies. Eventually, it is revealed that the culprit of the kidnapped babies was the Kamek from the future, and adult Bowser, who are after the Star Children. Because of an argument, Baby Bowser ends up helping the other babies in their journey. However, once they reach the end of Bowser's Castle, Baby Bowser betrays the Yoshi clan and the other babies, but is soon defeated. Bowser soon battles the Yoshi's because of what they did to his baby self. However, with the aid of the giant Yoshi eggs, Bowser was also defeated. However, he was then bloated up in size, where he proceeds to try to destroy the other Yoshi's. However, with teamwork between all four of the babies, the Yoshi's were able to defeat Bowser, who escaped back to his own time. Baby Luigi was rescued, and peace returned to Yoshi's Island.

Super Smash Bros. series
There are three different stages that have appeared in the Super Smash Bros. series, which are all based upon and entitled Yoshi's Island. They are all based off different games though, the first is based off Yoshi's Story, the second off Super Mario World and the final one off Super Mario World 2: Yoshi's Island.

Itadaki Street DS
Yoshi's Island is one of the various boards in the game Itadaki Street DS.

Fortune Street
Yoshi's Island reappears as a Mario series board in the sequel to Itadaki Street, Fortune Street. In Easy mode, the board, for the most part, makes the plyaers go one way because of the line shape of the board. In Standard mode, the board looks like three intersecting circles, with a big piece of land in the upper right hand corner. Both boards have a one way Flatbed Ferry to take to the other side of the board. In Tour mode, the player has to play against Toad, Yoshi, and Birdo.

Though Yoshi's Island is known for its Yoshi population, many other kinds of species live on the island as well, such as Goombas, Shy Guys, Rexes and Piranha Plants.
