Eyebrawl

Eyebrawl is a Duel mini-game that makes an appearance in Mario Party 8. Mr. Is and Big Mr. Is appear in the mini-game. However it is arguable if the big Mr. I seen in the game is Big Mr. I or it's just a Mr. I slightly bigger than the others.

Introduction
Two characters walk through some woods. The camera moves up showing the night and a big dark cloud. The dark cloud slowly moves away, revealing a full moon. The camera goes back to the ground and out of nowhere two Mr. Is appear! Both characters gasp and the mini-game starts.

Gameplay
The player must move the Wii Remote 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 Remote around. However in that Mr. I's place, another Mr. I (now slightly bigger) will appear. The player must then again move the Wii Remote 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 Wii Remote in circles around the Mr. I. It will then be defeated. The character that beats one of the big Mr. Is first will then get to the winner of the game.

Ending
After a character defeats the Mr. I, he or she will do his or her winning pose. However, tiny Mr. I's will then appear out of nowhere, just like how the first Mr. I's appeared. The winner will then scream and start running, and run off the screen. The loser will be too shocked to move, and the Mini Mr. Is surround him or her while the big Mr. I just looks at the loser. The loser will be left crying and screaming, and then the screen fades.

Trivia

 * The game might take place in Boo Woods, because these woods and Boo Woods both have creepy creatures and old and grayish trees.
 * The name of the mini-game is originated from the word, "Eyeball".
