Mario and Luigi are walking around Delfino Plaza, looking around and taking a break.
Luigi: Let's visit Sirena Beach!
Mario: Sure!
Mario and Luigi enter the pipe that leads to Sirena Beach. On the beach, they run all the way to the hotel.
Manager: Well now, Mario and Luigi! You both should really drop by the casino. I'll let my boys know that both of you are coming. Go on, now!
Luigi: Where's the casino?
Manager: See that Pianta in the corner over there? He'll let you in.
Mario and Luigi walk over to the Pianta.
Pianta: Ah, Mario and Luigi! Right this way, please!
The Mario Bros. take an elevator to the casino.
Luigi: Whoa! This place is huge!
Mario: Hey, you Pianta, what are we supposed do?
Pianta: This is the first time I've seen water-powered slots!
Luigi: What a hint! We must spray these giant slot machines!
Luigi tries spraying the slots, getting a Boo, a 7, and a coin.
Luigi: What do I do now?
FLUDD2: Spray the slots on the sides until you get 7s on both of them.
Luigi does that, and, eventually, gets 7s on the sides. Victory music plays.
Luigi: That means something good! I think I have to get triple 7s on the machine over there too.
Mario, who was already over there, sprays the slots and gets three pictures of a coin. A coin appears. Mario sprays the slots again, this time getting triple Boos.)
Mario: Uh oh...
An invisible Boo enters the room. Since Mario does not know where it is, he gets hit. He tries jumping onto it, but accidentally jumps into it.
Mario: Ouch...
Mario squirts the slots again.
Mario: This time I'll get it right!
Mario instead gets three coins, which heal him.)
Mario: Whee!
Luigi now goes over to spray the slots. He gets triple 7s. Victory music plays and a red curtain rises in another part of the room, showing a board with ? tiles.
Luigi: Let's spray these tiles!
Mario and Luigi spray the tiles, which start to flip. Some return to the ? side, but others turn to a new side. Mario sees that the picture, when completely formed, is that of a Shine Sprite.
Mario: Oh! We must spray them until they all are on the Shine side.
After a long while, the Mario Bros. are finally able to get all the tiles on the Shine side. Victory music plays, and the board rises. Behind it is a warp pipe. Mario and Luigi enter it and end up in an obstacle course.
Mario: Not another one!
The Mario Bros. see two giant cubes in front of them, moving back and forth in different directions. They go past when the cubes are far apart and jump onto another cube, which carries them to the next platform.
Luigi: Look at all the giant cubes!
The Mario Bros. head left, avoiding the giant cubes. Luigi crosses the bridge for a 1-Up. After getting it, he runs away to avoid getting sandwiched by three giant cubes.
Luigi: That was close!
Luigi follows Mario onto the spinning cube, which carries them to some wooden platforms. They easily cross those platforms and jump onto the spinning cube. Mario stops to grab the 1-Up, and Luigi jumps onto the final giant cube. Being careful not to fall off, he uses it to get to the platform with the Shine. He grabs it and does the Shine Sprite Dance.)
Luigi: Whee! Woohoo! Yahoo!
Mario: *sigh* Onto the next Shine!
