Super Mario World 2: Yoshi's Island is a 1995 platform game developed and published by Nintendo for the Super Nintendo Entertainment System (SNES). It is the sequel follow-up to Super Mario World. The player controls Yoshi, a friendly dinosaur, on a quest to reunite baby Mario with his brother Luigi, who has been kidnapped by Kamek. As a Super Mario series platformer, Yoshi runs and jumps to reach the end of the level while solving puzzles and collecting items with Mario's help. The game has a hand-drawn aesthetic and was the first in the franchise to have Yoshi as its main character, where it introduces his signature flutter jump and egg spawning abilities.

A platformer is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels with uneven terrain and suspended platforms of varying height that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, gliding through the air, or bouncing from springboards or trampolines.
