Super Mario World 2: Yoshi's Island is a 1995 platform video game developed and published by Nintendo for the Super Nintendo Entertainment System. Acting as a prequel to Super Mario World, the game casts players as Yoshi as he escorts Baby Mario through 48 levels in order to reunite him with his brother Luigi, who had been kidnapped by Baby Bowser's minions. As a Super Mario series platformer, Yoshi runs and jumps to reach the end of the level while solving puzzles and collecting items. In a style new to the series, the game has a hand-drawn aesthetic and is the first to have Yoshi as its main character. The game introduces his signature abilities to flutter jump, produce eggs from swallowed enemies, and transform into vehicles. It also features 2D graphics with Linear transformations (similar to Super Mario World).
The game's hand-drawn aesthetic—a style new to the series—descends from producer and Mario creator Shigeru Miyamoto's distaste for the computer pre-rendered graphics of the game's contemporary Donkey Kong Country. Yoshi's Island was released in Japan in August 1995, and worldwide two months later. Some of its special effects were powered by a new Super FX2 microchip. The game was rereleased for the Game Boy Advance with few changes in 2002 under the title Yoshi's Island: Super Mario Advance 3.
