Archaeologuess

Archaeologuess is the story Mini-game of Shy Guy and can only be played and unlocked when Shy Guy's Jungle Jam is completed in Mario Party 4. It is a game of odd-one-out that takes place in an ancient chamber. In the game, the player must determine which shape out of five has one difference from the other four. If a player were to guess incorrectly, the shape would fall down and flatten their character. A correct guess would send the shape flying towards the Shy Guy picture in the back of the room. The player wins by getting three correct guesses before their opponent.

Trivia
The mini-game name is a pun off the word "archaeologist".
