Super Mario World 2: Yoshi's Island

Super Mario World 2: Yoshi's Island (JP) is a 2D platform game for the Super Nintendo Entertainment System, developed by Nintendo EAD. The game is the prequel to Super Mario World and chronologically the first in Mario series, and it stars Yoshi and the Yoshi clan who, while carrying Baby Mario, travel across Yoshi's Island to rescue Baby Luigi from Baby Bowser and his Magikoopa minion/caretaker, Kamek. Instead of relying on jumping and a power-up system for combat as in the traditional Mario platformers, Yoshis use their tongue and eggs to overcome obstacles, as well as the introduction of many other different mechanics. The game is notable for introducing a time-based health system rather than hit points, an anomaly to what many platform games typically did in this game's time period. Rather than relying on powerful pre-rendered graphics as its contemporary, Donkey Kong Country did, Super Mario World 2: Yoshi's Island employs a very distinct, stylized arts and crafts style to stand on its own. The game makes use of the Super FX2 graphics chip (one of only four commercially-released SNES games to do so), which allows for larger, more detailed sprites and more advanced effects that emulate 3D space.

Although Super Mario World 2: Yoshi's Island was not as financially successful as its predecessor, the game's highly positive reception and unique style has spawned a new series of platform games from the Yoshi series, although it is the fourth entry overall. The game has received various adaptations into manga, such as receiving volumes dedicated to it in the Super Mario-Kun and Kodansha's Super Mario manga series and extensive merchandising. The game has received a remake on the Game Boy Advance, Yoshi's Island: Super Mario Advance 3, which was released on Virtual Console for Nintendo 3DS, with owners applicable for the Nintendo 3DS ambassador program being able to download the game for free, and Wii U. The original SNES version of Super Mario World 2: Yoshi's Island is included on the SNES Classic Edition, and although it has yet to be announced for release on Virtual Console on any other system, it is one of the 20 launch titles for Super Nintendo Entertainment System - Nintendo Switch Online on the Nintendo Switch.

In 2006, a direct sequel to the game was released called Yoshi's Island DS for the Nintendo DS. There was also a midquel called Yoshi's New Island for the Nintendo 3DS released in 2014.

It stars Yoshi and Baby Mario on their quest to save the recently kidnapped Baby Luigi. The game takes a dramatic turn from the previous Mario platformers and has been considered one of the greatest games ever released on the console.

Yoshi's Story for the Nintendo 64 features similar gameplay, though whether Nintendo considers it a sequel or not isn't clear, considering that the initial name was Yoshi's Island 2 for Yoshi's Island DS.
