Mario and Luigi run up the "endless" staircase and get to the Bowser picture.
Luigi: This is it!
Mario: This is where we get our 120th Star!
They jump in the hole.
Luigi: After you, Mario!
Mario: Thanks, Luigi!
Mario runs up the course.
Luigi: He's fast!
Luigi goes to the red coin above the box, but it is gone!
Luigi: Mario!
Luigi runs to get the coin on the platform but it is gone too! Luigi goes for the coin on the ledge but it is gone as well! He continues without a single red coin in hand!
Luigi: Maybe they are all in one place!
Luigi searches everywhere. Luigi gets to the top and finds the Star in Mario's hands!
Mario: Here we go!
Luigi: Did you get every red coin on your way here?
Mario: Yes!
Luigi: Yeah!
Mario: WE FINALLY HAVE ALL 120 STARS!
Luigi: Before we find out what 120 Stars can do, let's fight Bowser!
Mario and Luigi enter the pipe...
