Mario and Luigi come out of the Sirena Beach Warp Pipe after defeating King Boo.
Luigi: Whew. That was a little rough.
Mario: You said it. Need a refill?
Luigi: Yeah, let's go.
Mario: I'll wait here, my tank is full.
Luigi: Fine then.
After a refill they both go to Sirena Beach again. It's all covered in electric goop.
Mario: Mamamía!
Pianta: Oh Mario Brothers, help us! The whole beach is covered in this horrid goop!
Mario: Don't worry, we'll take care of it!
Pianta: But you must hurry! Some Piantas are in there! They'll surely die if you don't clean the goop in three minutes!
Mario: I said don't worry!
Luigi: Ready...
Mario: Set...
Mario and Luigi: GO!
Mario and Luigi both start cleaning up, but Mario accidentally falls on the paint.
Mario: BlagadiblagadiblagadiAAG!
Luigi: Don't worry, Mario! I'll save you! Hey, what are these barrels for? Wow! They're full of water!
Mario: BlagadiblagadiblagadiAAG!
Luigi grabs a barrel...
Mario: BlagadiblagadiblagadiAAG!
... and throws it at Mario. CRASH! SPLASH!
Mario: OW! You didn't need to throw it on my head!
Luigi: Oops. Hey look! We found a Pianta!
Pianta: Thanks! I thought I was a goner, but there's still two more that need saving.
Mario: Let's hurry up, we can use these barrels.
CRASH! SPLASH! CRASH! SPLASH! CRASH! SPLASH! CRASH! SPLASH!
Luigi: Another Pianta!
Pianta: Thanks man! I'm outta here!
Mario: We're almost done!
Luigi: But we're out of barrels!
Mario: Let's use FLUDD on what's left.
They manage to clean the goop and find the last Pianta just in time.
Pianta: Oh thank you, thank you, thank you! This kind of heroic behavior deserves a reward! Take this Shine!
Luigi: Oh boy, oh boy!
Mario does the Shine Dance.
Mario: Yahoo!
Luigi: Onto the next Shine!
