Well it obviously looks like the mario pipes but it's not ripped.
You will not find that specific pipe in any of the mario games, he created that asset himself and the game has nothing else to do with mario apart from, maybe, the color scheme or the design of that "bird" kind of looking mario-ish but that is wonky as hell since it's low-res art and you only have so many pixels to work with.
I find it hard to believe that nintendo can literally sue him because they own the rights of that specific green pipe and all of its variations, that they own the very concept of "green pipe" and "sprite that kinda looks like it could go into a mario game".
