This game genie code makes it so Mario swims all the time. The levels repeat and sometimes you get to an odd weird level! I love that! I want to try to find more weird levels and glitches in this game!! I recorded this more in high quality so I can make a better tiktok from it. When Mario swims around he can still hit blocks unlike most swim levels! Go for a running start and he can swim really fast! Hehe that's cool, never done that glitch before!!
Here's the clip. It ends abruptly but there is not much more to see. It repeats then goes to a castle where it froze while recording.
