Super Mario World 2: Yoshi's Island

Super Mario World 2: Yoshi's Island is the second game in the Super Mario World series, and the first game to star Yoshi. The game was later re-released for the Game Boy Advance under the title Super Mario Advance 3: Yoshi's Island. A heavily-criticized sequel, Yoshi Story, was released for the Nintendo 64, and a Nintendo DS sequel named Yoshi's Island DS was also released. Yoshi's Island is the first game to feature Mario as a baby.

Plot
One night, The Stork was carrying two babies across the sky. These two babies were Baby Mario and Baby Luigi, the future heroes of the Mushroom Kingdom. Suddenly, a strange figure, Kamek the Magikoopa, flew by on his broomstick and hit the stork. He snatched Baby Luigi, but the other baby fell down towards the ocean. When Kamek discovered his mistake, he sent his Toadies to find and capture the missing baby. Meanwhile, the other baby, Baby Mario, had fallen on Yoshi's Island on top of a Yoshi. Along with the baby fell a map, but the Yoshi could not make sense of it. He consulted his other Yoshi friends and told him what had happened. After some talking, the green Yoshi found out what the baby really wanted – he wanted to save his brother from Kamek. So the Yoshis decided to help the baby and they set out on an adventure to rescue Baby Luigi from Kamek and his Toadies.

Trivia

 * In the Super Mario-Kun adaptation of this game, Adult Mario and Adult Luigi go to the past with  Adult Bowser by mistake. They stop Kamek from kidnapping Baby Mario and help Yoshi reunite the Baby Bros. But, in the Donkey Kong Country adaptation of Super Mario-kun, it is revealed Yoshi does not remember anything about any Adults here and nothing about the Baby Mario tantrums.
