Mario and Peach are taking a walk, and suddenly Spiny Eggs start falling from the sky. A few land around Peach and hatch, trapping her. They escape with Mario chasing them.
After going through 7 worlds, killing Bowser on the way, Mario ends up at Peach's cage. He's about to free her when Dry Bowser emerged from the lava and blasted Mario to the other side of the bridge, giving him a blue Koopa shell. D Bowser jumps on the bridge switch and starts throwing bones at Mario. Mario hides in his shell, which deflected the bones which hit D Bowser. Soon D Bowser falls into the lava and lands on a switch that was in there. It makes the castle crumble! Mario grabs Peach's cage and the key and runs out of the castle, then watches as Bowser's Castle collapses on top of D Bowser and Bowser Jr.. He then frees Peach and the credits begin.
After the credits, Bowser Jr. emerges from the Bowser's Castle ruins with D Bowser's bones. He drops them into a magic pot nearby Kamek, which causes them to become Bowser again.
