Eyebrawl

Eyebrawl is a Duel minigame that makes an appearance in Mario Party 8. Its name is a pun on "eyeball". Mr. Is appear in the minigame, including one large individual that may be a Big Mr. I.

Introduction
The players are running into a dark forest, when they come to a pause. The camera moves up, showing a dark cloud in the night sky. The dark cloud slowly moves away, revealing a full moon. The camera then pans back to the two characters, as two Mr. I's appear, causing both characters gasp in shock.

Gameplay
The player must move the in circles around a Mr. I's head about three or more times, until that Mr. I is defeated (à la Eye Sore). Precise movements are encouraged, not just frantically moving the around. However in that Mr. I's place, another Mr. I (now slightly bigger) will appear. The player must then again move the in circles around the Mr. I.

Then after that Mr. I is defeated, a big Mr. I will appear and the player must then move the in circles around the Mr. I. It will then be defeated. The character that beats one of the big Mr. Is first will then be the winner of the game.

Ending
After the player defeats the Mr. I, they will do their winning pose, until several tiny Mr. I's appear out of nowhere just like the first Mr. I's, scaring the winning player off while the Mr. I's surround the losing player.
