Most of the mini-games in Mario Party are pretty inoffensive -- except for this one called "Eyebrawl." It's just ... actually, there's no way to describe it. The game starts with the characters walking into dark woods at night -- which in itself is pretty suspect -- when these inexplicable floating eyeball creatures come from out of nowhere.
Mario games should not remind us that scene in The Shining.
The Super Mario Wiki informs us that the floating eyes appeared before in Mario 64, which is odd, because we don't remember them from anything except our nightmares. The objective of the mini-game is to move the wiimote in circles, making the eyes dizzy as they eerily follow your every movement with their, um, selves.
"Oh God -- everyone's watching! It's just like being at the mall!"
