In Mario 64, before the start button screen shows, you have some kind of mini-game where you could strech marios face in many ways.
Did that mini game do anything? Had any effect on the main game? Or was it just for show/fun?
I think I've heard somewhere that some stretch patterns would be cheatcodes, but couldn't find confirmation anywhere.

This is the only thing I could find in a quick search. It seems unlikely to be a method for entering cheat codes as there are countless ways and degrees to stretch Mario's face, so there doesn't seem to be a way to put in a precise pre-defined stretch combination.
