This is a quick completion of Super Mario World 2: Yoshi's Island.
Here, the author, Masterjun, abuses a glitch that causes Yoshi's tongue to extend infinitely. This confuses the game and causes it to jump to the SNES CPU registers and start executing arbitrary code, which triggers the credits.
There is also a run without game-breaking glitches and a 100% run.
Exploiting this glitch instead of a glitch that results in corruption of the egg list saved 01:19.27 over the previous movie.
