Pannenkoek2012 then proceeds to inspect the eye mechanics of all blinking characters, distinguishing between five various patterns that different characters exhibit throughout the game.

One of the YouTuber’s most captivating discoveries is perhaps how Mario and Princess Peach seem to blink in sync. It’s a nice touch on Nintendo’s part given the dynamics between these two; as Pannenkoek says, “it’s actually kind of romantic.”
