Mario and Luigi are deciding where to go next. Because they now have the necessary Stars to go to the second course, they do so.
Mario: Hey, Luigi! Let's go to this portrait!
Luigi: Ok.
Mario jumps into a REAL painting and bumps his head.
Mario: OW!!!
Luigi: Hahaha!!! It's this one!
Luigi enters the right painting followed by Mario. They land in a grassy area and see a huge fortress above them. They both go up a ramp and jump over some blocks coming out of the wall, then jump over some moving platforms. They get to a place that there are some Thwomps above large stairs.
Mario: Hey Luigi! Look over there! A Star!
Luigi: Huh?! Where?!
Mario flings Luigi below a Thwomp. SQUISH!!! Luigi becomes a pancake.
Luigi: What did you do that for?!
Mario: You laughed at me, so HAHAHA!!!
Luigi sits in a corner, sobbing. Suddenly he warps.
Luigi: MAMA MIA!!!
Mario: Mama MIA!
Mario stands in the corner where Luigi was and gets warped to a very high part of the fortress. Luigi is stomping on a Whomp and collects the coins.
Mario: Let's-a go!
Luigi: ...
Mario climbs a bit and gets to the highest part of the fortress. There, he sees a huge Whomp.
King Whomp: OOR OOR!
Mario stands in front of King Whomp, and when King Whomp is about to fall on him, he dodges. When King Whomp hits the floor, Mario stomps on him. Then Luigi gets there. He repeats the process and hits Whomp a second time. Mario then finishes Whomp off. As Mario hits Whomp, a Star appears, and while Mario is getting off the floor following his stomp, Luigi jumps and grabs it.
Luigi: Here we go!!!
Mario: ... On to the next Star.
