Baby Bowser and Kamek are looking up at the stars at night, talking to each other. Baby Bowser says that he wants to have a planet someday. One with lots of Green Donkeys, even more toys, and no Marios. Kamek then says that he can take care of that. He swings his wand around and around, creating a giant, flying ship, and tells Bowser to hop in. He does, and the two take off. Meanwhile, all the Yoshis are going to bed, protecting the baby Mario Bros, when they all get kidnaped! Some yoshis happen to get away, but they know that they have to save their friends, family, and the Baby Mario Bros. So, they all go off to find White Shy Guy to ask him for help. Once they find him, they ask for help, and tell him what happened. White Shy Guy then uses magic to make them a ship. It looks like a couple of apples bunched together, so they call it the S.O.S. Apple. They then go into space to save their friends.
