Mario and Luigi just defeated Bowser a few hours ago.
Mario: Where to now?
Luigi: How about the Airstrip?
Mario: Ok!
Mario and Luigi go to the Airstrip Boat.
Pianta: Shall I take you to the Airstrip? It's only 10 coins!
Luigi: *sigh* I'll just swim to the Airstrip...
Luigi swims to the Airstrip.
Pianta: There are many coins in the sewers!
Mario: Ok! I'll look there!
Mario gets into the sewers and collects ten coins as shown:
Mario: Done!
Pianta: Let's go!
Mario gets on the boat and they soon come to Luigi.
Mario: Better catch up, Luigi!
Luigi: Oh c'mon!
Luigi gets on the boat and they all go to the Airstrip.
Pianta: Whee! What great weather!
Mario and Luigi both grab a Turbo Nozzle and bash the gate.
Luigi:There's a blue coin in there!
Mario sprays the ice block and gets the blue coin.
Luigi: Hey! A switch!
Luigi pounds the switch.
Voice: Get all eight red coins before times up! Good luck!
Mario: Let's-a go!
Both Brothers get the red coins on the strip.
Strollin' Stu: Get 'em!
Mario hits the Stus so hard that they all fall in he water!
Mario: Which way should we go?
Luigi: You go under the bridge and I jump the boats. I'm a better jumper than you!
Mario: I'M A BETTER WALL KICKER!
Mario gets the red coin and turns left to get the red coins there. They now have 6.
Voice: One minute left!
Luigi turns right and jumps the boats when the Shine appears!
Luigi: My Shine!
Mario turns successfully with no crashes and grabs the Shine. But Luigi hits a tree.
Luigi: Ow!
Mario: Wahha!
Luigi: Onto the next...
Luigi faints.
Luigi: Shine... Sprite...
Mario: You should've checked the sewers for coins!
Luigi hits himself on the head.
Luigi: I'm so stupid!
Pianta: I can take you back for free!
Luigi: All right!
Pianta: And you owe me ten coins for getting on the boat.
Luigi: At least I got some during the red coin challenge!
Luigi pays and both Brothers go back
to Delfino Plaza to search for more secret Shines.
