Mario and Luigi go to the water portal room and jump into the hole.
Mario: Toss me!
Luigi: No!
Mario picks up Luigi and hangs him over the lava!
Luigi: All right!
Luigi throws Mario across and then uses the platform to get across.
Bully: This time you will give me your lunch coins!
Mario collects some coins and throws them at the Bully so hard he falls off.
Bully: AAAAA!!!
Mario gets the red coin by walking on the scaffold. Luigi continues on up to get the next three red coins. He gets two but had to fall to get the second one. Mario continues on up and gets the rest of the red coins and then the Star.
Mario: Here we go!
Luigi: Oh c'mon!
Mario: Let's-a move on!
