Mario and Luigi materialize back in Delfino Plaza.
Mario: Whee! That was fun!
Luigi: Yeah, I guess... Where's that Yoshi egg? I wanna ride Yoshi!
Mario: No! It's my turn!
The duo split up and search for the egg, as they both forgot where it is. Luigi finds it first.
Luigi: (whispering to himself) Hmm, Yoshi wants a banana, eh? I'll fetch one.
Meanwhile, Mario is collecting all the fruit he can carry and is about to climb back onto a rooftop.
Mario: Aha! I spot it! It wants bananas! I HAVE SOME!!!
Luigi, who now has a banana, realises Mario has found the egg and has a banana, and dashes as fast as he can towards the egg with his banana. Mario chucks his banana from a nearby rooftop to the egg. It hatches, but by this time Luigi has jumped on the roof and is now riding the Yoshi.
Mario: No fair!
Yoshi: Mmm, Yoshi spot pineapple in chimney! Yoshi eat!
Yoshi starts hovering towards the pineapple. He lashes out his tongue, and eats the pineapple.
Mario: HEY! A WARP PIPE! LETS GO!
Mario and Luigi (and Yoshi, who disappears during the dematerialization), jump into the warp pipe. They end up in Sirena Beach.
Mario: Hey... where are we?
Luigi: WHERE'S YOSHI?!
Pianta: This is Sirena Beach! Home of Hotel Delfino. Well, it used to be.
Mario: What do you mean "used to be"?
Pianta: Go talk to the Hotel Manager, over there.
Mario and Luigi run towards the Hotel Manager. Luigi slips and falls into some electric goop.
Luigi: AAAAWAGHIGAH!
Mario squirts the goop and Luigi gets up, slightly singed.
Luigi: Whew, thanks.
Mario: No problem. Lets get to the Manager!
The pair run up to the Manager.
Manager: Oh, please tell me my nightmare is over! You can save me! I don't know why, but you just look very... capable to me. Listen... it all started around noon. This giant manta-shaped... thing showed up! It was paper-thin... a floating silhoutte. It came and covered the hotel grounds in electric goop. Then... Oh, the horror! My beautiful hotel! My poor building!
The Manager bursts into tears.
Luigi: What happened to it?!
Manager: *sniff* It sank in the middle of that awful ooze! Why me? WHY?! Now I've got the staff cleaning up, but where's my hotel? What am I supposed to do? I can't just sit back and-
A rumble is heard, and the Hotel Manager looks around.
Manager: AIIIIGH! It's back! That gossamer ghoul! Do something!
A giant manta-shaped silhoutte creeps onto the beach, oozing electric goop like a snail wherever it goes. It heads towards Mario and Luigi!
Luigi: Squirt it, Mario!
Luigi and Mario both squirt the "manta-thing". It groans a bit, and sparks fly off it, but it continues creeping up on the duo.
Mario: RUN FOR IT!!!
Mario dashes away quickly, whilst Luigi jumps and hovers over it, inadvertantly squirting it. It soon, after lots of groaning, splits into two smaller, faster "manta-things". One chases Mario, the other goes for Luigi.
FLUDD2: Luigi. Spraying it with water, causes it to divide.
Luigi: Is that bad?
FLUDD2: No. Good. Keep spraying.
Mario continues to run away from the "manta-thing" whereas Luigi keeps squirting it until it divides into even smaller, faster "manta-things".
FLUDD2: Keep doing this, and it will soon be finished.
Luigi: But it's not working! it's just getting more annoying!
FLUDD2: Listen to me, and keep going.
Luigi: Fine!
Mario suddenly trips and falls, and the "manta-thing" chasing him surrounds him in electric goop.
Mario: AAAAGAWHISHA!
Luigi doesn't realize what has happened, and continues spraying the "manta-things". Mario soon loses a life and dematerializes.
Mario: Luiiigiiiiiii...
Luigi: Mario?! Where are you?! OH NO!!! Mariooooo...! I'll have to fight them myself! TO AVENGE MY BROTHER!!!
Luigi soon squirts all the larger "manta-things".
FLUDD2: They are dividing into smaller units.
Luigi runs out of water and rushes to the ocean edge to refill. He decides to continue from there so he doesn't have to worry about water. After a while, he has squirted all the medium-sized "manta-things" and they all turn dark pink.
FLUDD2: Now they are all after you. Beware Luigi.
Luigi: Ok!
Luigi runs around like a maniac, squirting, hovering, screaming, and jumping until they are all gone! Suddenly, Hotel Delfino grows out of the ground, and a Shine follows.
Luigi: I did it!
Luigi grabs the Shine and does the Shine Sprite Dance!
Luigi: Yahoo!
Luigi dematerializes and rematerializes back in Delfino Square, where he meets Mario.
Mario: You're back! Did you save the hotel?
Luigi: Yep! And for once, I got to do the Shine Sprite Dance! So there! NYAH!
Mario starts grumbling...
