Hey everyone, I have reasons to believe that Mario Vs. Yoshi is stolen.

Well, to begin with, the creator have just made his account and of the four submissions he have, one is a poorly animated American flag, another is a loop of a TBBT clip, both don't require any animation skills and anyone who had saw his account before today would believe he can't animate.

Also, there is a game in his account, where it says "2003 GameRival", and first of all, why would he upload a 2003 game in 2012? Of course he could do that, but considering this guy's writing skills, I really doubt he had any more than 7 years in 2003, so it's not likely he was able to pull off a game like that.
Specially because he uploaded another GAME that is actually an ANIMATION of a looping flag, why would he do that?
Also notice that the medals in the Tower Blaster game DO NOT work, why not? Well because he would need the original file to implement the medals into the code, so it would interact with the portal, but that doesn't happen, because he doesn't have the original .FLA file, simple like that.

Now, other thing that looks VERY, VERY amateurish is the thumbnail for the video, anyone would use an actual scene from the flash, and not THE FOURTH THING YOU FIND ON GOOGLE IMAGES WHEN YOU SEARCH FOR "Mario Vs. Yoshi"

About his user image, it was done by NINTENDRAWER at DeviantArt:
http://nintendrawer.deviantart.com/art/mario-and -peach-114260764
Why wouldn't he draw his own user image if he had all that skill for animation?
Also notice how he cuts the image over the watermark.
I found it searching for "Mario loves Peach" on Google images, it is the fifth image.
Also he isn't Nintendrawer! He would have that animation at his DeviantArt account if he was. And Nintendrawer have proper English skills.

Now, where would he have gotten the animation?

Look at the comments, one was made January third, and the other February second, that means after that time ANYONE could get it and upload it to newgrounds pretending it is their own, and no surprise someone did in such short period of time, it doesn't have credits or preloader after all, why not have a preloader in newgrounds? That's also rare.

Here's another site with the same animation: http://swfchan.com/17/84896/
notice how it says it was there since 2010. Again, even if it is possible to upload after so many years, it doesn't usually happen.

And what is that badly cut montage with Luigi with a hat in his profile?
And why is it rated M and have so many people credited with him? And notice how MarioKirbyLink100 who is co-authored had the same behavior of putting a short animation (pretty bad by the way, rated 1 star) as a game with medals that you can't get.

Even the flash's short description is absurd:"Now there fighting who will win"
Really?

Just look at the size of this text, I wouldn't make all that up, there are lots of reasons for me to believe he stole it, and his behavior is very similar to lots of fake profiles I've seen.

So, my reasons are:

He submitted something horrible in a week, and something amazing in the next one, as if he got good all of a sudden.
The game he uploaded says "2003 GameRival", a website that I never saw uploading anything to newgrounds, and uploading it 9 years later is very odd!
His user icon wasn't done by himself.
The original animation is around at least since 2010, as you can see in the link I provided.
The medals on his game don't work, as if he was trying to put them just as cover.
The image in his news post is absurdly bad for someone who supposedly can make something as amazing as that animation.
The flash has no proper thumbnail, instead, it have something I found pretty fast at Google and have Mario from Super Mario Sunshine, which makes no sense and resembles all those amateur animations made with only pictures.
His co-authoring makes no sense and his friends are equally bad.
His other submissions are garbage.

If CazaZach is actually the author, then I apologize for all this.

EDIT: Apparently it was made by DogmanSP at DeviantArt, someone who have decent grammar: http://dogmansp.deviantart.com/gallery/?offset=7 2#/d26k2ni
END OF EDIT.

EDIT:

The submission was removed.

CASE CLOSED!
You can hire me as a private detective if you want.
