Mario and Wario are hanging around with the Toad Brigade.
Rosalina: So, are you ready to travel to the center of the universe?
Mario and Wario: Yes we are.
Rosalina: Then let's go!
The Comet Observatory powers up and flies to the center of the universe.
Mario: What do we do now?
Luma: Stand in that gravity pull light.
They do so and make it to another planet with lava and platforms on it.
Mario: Let's get going!
They make it across the lava planet and to a planet with ice platforms.
Wario: Let's skate across.
They skate across the ice planet and come to a planet with poison sand.
Mario: This looks scary.
Wario: No time to chat, we've got to move!
They make it to a part with blue platforms.
Mario: I can sense Bowser is up ahead.
They then come to a fire funnel.
Mario: Let's be extra careful when we get through this funnel.
Wario: Got it.
They find where Bowser is. Just then Junior flies in front of them with Peach and Daisy.
Junior: Looking for Princess Peach and Daisy? Too bad! 'Cause they're with me!
Peach: Mario!
Daisy: Wario!
They start jumping up the stairs, then fireballs start coming down!
Bowser: Finally! You got here just in time to see the creation of my galaxy in the center of the universe! Watch and weep! From this galaxy, I'll rule a great galactic empire with Peach and Daisy by my side! It will last forever! I will rule every corner of the universe! As you can see, Mario and Wario, stomping you is at the top of my list!
He stomps and he, Mario, and Wario are warped to another planet.
Mario: Let's get him!
Wario: Yeah!
Bowser starts jumping and sending electric waves towards our heroes, then turns into a boulder and starts rolling.
Mario: His weak part is his head!
Wario bumps him on the head. They are then warped to another planet, where Bowser starts breathing fireballs.
Mario: How are we gonna get him when he's in the shell?
Wario: I got it!
Wario flings a plant at him. Then they are warped into Bowser's sun.
Mario: This shot is for the universe!
Mario star spins Bowser and he falls off the planet.
Wario: Look! The Grand Star!
They grab the Grand Star and rescue Peach and Daisy.
Peach and Daisy: Good grief!
Just then the 2 Lumas that accompanied Mario and Wario along with the other Lumas fly into the black hole to stop it.
Wario: Wait!
Just then the black hole explodes. Roaslina somehow saves Mario, Wario, Peach, and Daisy, and tells them how the baby stars will grow up to become galaxies, and that the cycle never repeats itself the same way.
Later Mario, Wario, Peach, Daisy, and Bowser wake up in the Mushroom Kingdom. Mario and Wario see something green in the sky.
Mario and Wario: Welcome! Welcome new
galaxy!
