A long, long time ago, a stork flies into the sky carrying two little infant plumbers over to New Donk City. But a Koopa Wizard swoops in to capture the babies away. One is taken while the other descends below into Yoshi's Island. The little Yoshis find Baby Mario alone and help him try to find and rescue his baby brother Luigi in Kamek's Castle. Along the way more babies lost in Yoshi's Island all share a connection with Baby Mario. They are the Star Children.
