Mushroom Medic

Mushroom Medic is a mini-game played in the Extra Room in Mario Party 4. In this game, five characters enter a hospital: Either a Toad, Goomba, Boo, Shy Guy, or Koopa Troopa. Each of them is given a Poison Mushroom, but only one of the patients is infected. It's up to the player to find the critical one. To identify who it is, the player must move the cursor from patient to patient, and see which one's heart beat is different from all the others. This depends on how the controller rumbles. If the player gives a pill to the right patient, the player gets another set of them and repeat. If the player doesn't do it in time, or give the pill to the wrong patient, the critical one passes out and the mini-game will end.

Trivia

 * The game is possibly a pun on "Emergency Room medic".
