Super Mario-Kun volume 22 is probably the most disgusting Mario media I've looked at. It's disgusting, even for Super Mario-Kun standards. Super Mario-Kun usually does bodily humor occasionally, but I think volume 22 has a lot of it.
- Page 12 has a Hammer Bros., perched on a cloud and pooping out projectiles
- Page 21 has Bowser surprise farting
- Page 42 Mario, before getting hit in the head by a spear, slides his head and his head goes through his crotch. I think this gag is repeated in the manga, but I'll note that anyway.
- Chapter 6 is probably the worst thing here. Mario, Wario, Luigi, and Yoshi are on a tightrope, in that order. Mario sprays something on Wario's eyes, I don't know. After this, I think Mario accidentally farts and Wario falls off. Later on, Luigi sees Mario pokes Mario's butt and Mario is seen straining. Mario then takes a big dump on top of Luigi and Luigi falls off. Mario starts crying afterward so I also think it's accidental. Then, I think some giant slime monster shoots cannonballs at Yoshi. Yoshi eats them all and is filled up. Mario fights this slime monster, but how he defeats the monster is by jumping on Yoshi and having a lot of stuff spew out of Yoshi's rear end into the monster's face.
- Page 85; Mario is involved in a crane game and Bowser holds Luigi and Wario hostage as toys in there and Yoshi controls Mario. At page 85, Mario is lowered into Wario's face and kisses him lip-by-lip. Wario has heart eyes and Mario has complete disgust.
- In page 99, there is Wario (transformed into a machine) bending over and opening a hatch and letting loose poop., cannonballs coming from his nose, and I think farting and afterward, there is a panel that's extremely low-res, you can see individual pixels. IDK if that's censorship or not.
- In page 115-117, a friendly Bob-omb jabs a pump into Bowser's rear end and pumps Bowser until Bowser explodes, akin to that Mario Party minigame of blowing up Bowser balloons.
- In page 124, Mario pisses on tied-up Bob-ombs. When characters piss in the manga, they never take their pants down, so I guess thank goodness for that?
- In page 132, Yoshi takes a big dump on Spinies after the other Yoshis fight the Spinies.
- Farting Boo at page 149.
Though there are some better stuff in there like Mario teaming up with Wario and Wario slams onto Mario to transform him into Bouncy Mario. Mario even imitates the Bouncy Wario artwork from Wario Land II. I also like how there is a narrative spun into some of the minigames, like the minigame where you fish for coins. In that one, the characters pull up a giant Cheep Cheep who essentially eats everyone.
Oh and I guess I'll add that in volume 37, Francis eats Mario. Bowser, who I think can control Mario by picking up a Wii Remote, shakes the Wii Remote really hard. You then see Mario's face poking out of Francic's rear end, page 150.
Anyone more versed in manga, especially children's ones, know how the possible French and Spanish translations will work out? I don't think this stuff jives well for the more "Western" audience. But again, there is a cross-dressing Wario in page 167.
