Peach and the Toads are in the desert and are out of water. The Toads see a bunch of clouds and start to do a Rain Dance. They're actually Lakitu clouds and start to drop Spinys. This is made funnier when one of the Toads thinks they did the wrong dance.
Floyd: That's the story in a nutshell— or should I say, eggshell.
Mario and Luigi buy a Yoshi translation book at the bargain price of 10 coins (which was originally 3000 coins, but discounted since they're "friends of Yoshi"). It's made funnier when every phrase in the book translates to "Yoshi".
Mario Bros.: Wait 'til I get my hands on that Friendly Floyd!!
Mario and Luigi rolling up the bottom right of the chapter's last page. Luigi then says that Peach "stole the spotlight this month".note The comic was originally released in Nintendo Power, which was a monthly magazine. Oddly, every reference to the one month span between issues (such as this one) was unchanged in the graphic novel version.
Early in the chapter, Mario gets shot to Bowser's castle by a Bullet Bill. He says this gem.
Mario: This must be the Koopa Express!
Peach waking up and seeing this image◊ in her face.
Mario asks Luigi if they survived the fall. Luigi then tells him not to ask. Made funnier by the fact that his head is underground.
This scene when Mario thinks that the haunted house they found is a trap.
Mario: I'm telling you, Weege, I have a weird feeling about this...
Koopalings: THE JIG'S UP— THEY KNOW IT'S A TRAP!
Bowser:Mark my words! They're tired, hungry, and, best of all, lost. This cozy little bungalow is just too tempting for a snoopy pair like the Mario Bros.. And it's unlocked, which makes it irresistible!
Mario:Wait, Luigi. We may be tired, lost, and worst of all, hungry. But we must keep our wits about us. There's something strange about this place... My Gut Feeling is that it's a trap! C'mon— let's get out of here.
(cut to the Koopalings and Bowser looking disappointed)
Mario dressing up as Dr. Mario and Luigi dressing up as a nurse, which is Hilarious in Hindsight, because an actual game called "Dr. Luigi" was released years after the comic.
Luigi telling Mario not to look down as he's standing on the snout of a Blargg.
The narrator reading the recap for the last chapter. It seems normal until the last sentence.
