After messing up all of Sans's memory data beyond recognition by hacking into the program, you, the player, reopen the game to see what has changed. Sure enough, something has.
This is just a scrapped animation I made earlier in the year that I was originally going to use as the intro cutscene for the VHS Sans OST. But I lost interest over time (sadly), and kinda forgot to post what I'd made so far.
