Mario and Luigi swim to the island with a warp pipe.
Luigi: Let's get in there!
Luigi sprays the orange juice generator but nothing happens.
Mario: You need juice for that!
Luigi goes over to the Yoshi egg and finds out it wants a pineapple. Mario returns with a pineapple.
Luigi: How'd you know he wanted a pipeapple?
Mario: I checked him earlier!
Mario gives the pineapple to Yoshi.
Yoshi: #$%#$%!!!
Mario gets on Yoshi and rides a boat to a coconut island.
Mario: Go to the island with the pipe, ok?
Luigi: Ok.
Mario leaves Yoshi on the island to eat coconuts until the second boat comes.
Mario: Here we go!
Mario and Yoshi board the second boat all the way to the platform in the middle of the ocean. Yoshi eats the banana that respawns over and over. Then the third boat comes.
Mario: Yes!
Yoshi: #$#$#@$%!
Yoshi boards the third boat and they both make it to the island.
Luigi: It's about time!
Yoshi sprays the generator and it vanishes! Then both Bros. go in the pipe.
Mario: A river of water with red coins?
Luigi: Yes! Now I can swim!
Mario: LUIGI! NOO!
Luigi: Why?
Mario: The skull and crossbones means the water is toxic!
Luigi: Oh.
Mario: See? That lilypad is dried up!
Mario gets on the lilypad and gets all the red coins exept the one in midair.
Mario: Hey! Another pipe!
Voice: This pipe takes you back to Delfino Plaza, and the entrance pipe will be closed again with a generator!
Mario: Oh.
Mario sprays the water with his FLUDD but there's too much toxic water! Luigi rides the brown lilypad and uses hover mode with his FLUDD2 to get the last red coin! But then he falls in the toxic water.
Luigi: AAAAAAAAHHHHHH!!! THE HORROR!!! HEEEEEELPPPPP!!!
Luigi reappears back at the start and comes back. Mario grabs the Shine Sprite and does the Shine Dance.
Mario: Yahoo!
Luigi: On to the next Shine!
