Luigi talks to Mario before they go for the 100-coin Star in the lava world.
Luigi: YOU KILLED ME OFF MANY TIMES!!! PREPARE TO DIE!!!
Luigi grabs Mario and throws him into the corner of the castle. Mario loses his hat and dies.
Bowser: HAHAHAHAHAHAHAHAHAHAHA!!!
Mario: THAT'S THE LAST TIME I'M KILLING YOU!!!
Luigi: Good!
With Mario still having his hat after the "glitch", both Bros. jump into the painting.
Mario: My shell!
Mario grabs the shell and goes out and about, collecting 50 coins from the ramps and under the bridge.
Luigi kills a Bully and gets 1 coin.
Then he goes to both Mr. Is and kills them for 10 coins.
Then he gets the 8 red coins on the tile puzzle, making 27 coins total.
Then he waits for the puzzle to complete and gets 8 coins to make 35.
Mario: There are 26 coins in the volcano! Meet you there!
They both go into the volcano. Luigi gathers 15 coins more to make 100 total for both.
Mario: My Star!
Luigi: Don't even think about it!
Mario: Your Star?
Luigi grabs the Star and finally does the Star dance.
Luigi: Here we go!
Mario: On to the next world!
Luigi: Ok, but if you kill me off once more I'm punching you so hard you will lose half your health!
Mario: Ok, but on one condition.
Luigi: What is it?
Mario: Let's take turns getting a Star!
Luigi: Ok, to Shifting Sand Land! AWAY!
