Also google translating the website is fun.

Mario & Luigi adventure in the body of Kuppa, Koppa to adventure the kingdom of mushrooms without knowing it. Each action is the key to save the Kingdom of Mushrooms! What? Proceed with each other!

Awesome "Metachoro Disease" was
also spreading to Kupa Castle · · · ·!
It got up to save everyone,
Selfish little Bunny 's Kupa Jr.! !

It's really annoying when they flatten his snout like they do in this other artwork of him. It's too extremely foreshortened.

[Mario's Drunken Holiday Special]

God Bowser looks like he lost weight.

[Waterfall of Flab]

Ewwww he looks so weird.

I loved reading the translations. I also liked the ones where they called Bowser "Satan" and Bowser Jr. "Buddha" lol

Google translating official sites and Japanese Wikipedia is a comedy gold mine.
Case in point, Mad Scienstein's description on the JP wikipedia's WL3 page translates to:

Mad-city
I attack by using drugs that become transparent humans when I touch them.

Anyways,

Well....

[Mcmadness]

I can't tell if the attacks are faster or slower.

[Doc von Schmeltwick]

The Goombas look more like their in a ball on the thumbnail, at any rate, instead of just in a circle.

[Mister Wu]

I have a bad feeling about this picture...

[Doc von Schmeltwick]

As do I about this one. Where were these colorful Dragon Ball villains in the original?

[Mcmadness]

I have a bad feeling about this picture...

Whats wrong with it?

[Doc von Schmeltwick]

The butt-slapper's the boss of the enemy team?

[Mister Wu]

Rehaving the same brainwashed Koopalings plot doesn't look too enticing to me, hopefully it's just a red herring and this time the plot doesn't revolve around rescuing them from brainwashing... again.

Iggy probably rebelled because it's an opportunity to kill Piranha Plants out of revenge that his hair is no longer the only plant in Smash. Though, Wendy is the boss here it seems.

Considering Brainwashing was a factor in the Koopa Troop turning against Bowser himself (along with Morton having an aura) I feel that's likely.
At the same time, a plot point of the story is that the Koopalings get fed up with Junior's arrogance and attitude towards them so it's not entirely unlikely that some fights at least will be them willingly revolting.

So, at the moment I'm pretty convinced those 3 are going to be the antagonists of Bowser jr's story alongside Fawful.

But do they work for Fawful? Are they 3 schmoes trying to do their own thing? Or am I completely wrong and they are just amusing side characters?
