After receiving an invitation from Princess Peach to visit and eat cake, Mario, Luigi and Wario travel to the royal castle, but when they get there, nobody's home. Yoshi, napping on the roof of the castle, wakes up and realizes the castle is somehow different and eerily silent. When Yoshi enters the castle to check things out, he discovers that Bowser has pilfered the castle's Power Stars and imprisoned the Toads in the castle's sizable collection of paintings. It's up to the dynamic dino Yoshi to save the day and figure out where Mario, Luigi and Wario disappeared to.
