Yoshi's Island DS (JP) is a Nintendo DS video game that is a sequel to the Super Nintendo Entertainment System video game Super Mario World 2: Yoshi's Island. It features several new features including new babies that grant Yoshi new abilities. The game world spans both screens of the Nintendo DS, with boss battles taking place on both screens. The game not only features Mario, Luigi and Bowser as infants, but also features Princess Peach, Donkey Kong, and Wario as infants too.
Once a floating island appears over Yoshi's Island, all the kids (including Baby Luigi) on Yoshi's Island get kidnapped by Kamek. The stork manages to save Baby Mario and Baby Peach, though, and gives the duo to Yoshi. Now, the three must go off and save the other babies.
After completing World 1, Baby Peach is kidnapped by a pair of Ukikis, and then suddenly Baby Donkey Kong jumps on Yoshi's back and decides to help save her. Once they do, the five (including the Stork), get struck by a huge tidal wave, separating the babies from Yoshi. Right then, Baby Wario falls out of the sky and helps Yoshi find the others. After defeating Bowser, Baby Luigi and all the kids are rescued and returned to their respective homes, except for Baby Wario, who appears to be a homeless orphaned baby. At the end of the game, it is revealed that Baby Mario, Baby Peach, Baby Donkey Kong, Baby Wario, Baby Bowser, Baby Luigi, and Baby Yoshi are the seven Star Children.
Like in the first game, Yoshi will be able to use his classic egg throwing move. To create eggs, you can either eat and swallow an enemy, or hit an egg block to gain them. He will also be able to use his flutter-kick that allows him to get to higher grounds. The Yoshis will be able to use their tongue to either eat enemies, or spit them out as projectiles. Like all the Yoshi games, there are multiple Yoshis throughout the game with each having different colors. Unlike some other Yoshi games, the color of the Yoshi will not affect the gameplay in any way.
There are five different babies in Yoshi's Island DS, each with their own abilities. The babies include Baby Mario, Baby Peach, Baby Donkey Kong, Baby Wario, and Baby Bowser. In the end of the game, Baby Yoshi and Baby Luigi appear, though they aren't playable characters nor have abilities. Their abilities are listed below:

Like the original game, this game will feature five hidden flowers in each stage that, if all collected, will give you bonuses and a ton of extra points. There will also be twenty hidden Red Coins that you can collect as well, that look exactly like standard Coins and will only reveal their true identity once collected. New to the game are character Coins that have a picture of one of the babies on it, which will either be Baby Mario, Peach, Donkey Kong, or Wario. The only character that can collect the Coin is the baby with there picture on it, so if it has Mario's face, then he is the only one that can collect it.
Stars are also in the game, which not only gives you more points, but also gives your baby more floating time.
