Bowser Card

The Bowser Card is a type of card that only appears in Mario Party: Island Tour, on the board Shy Guy's Shuffle City. It appears as a red and black card with Bowser's face on it, possibly hinting it wasn't supposed to appear normally, but was added by Bowser himself. It is a card that must be avoided, as it causes nothing but trouble.

Purpose
At the start of the game, after Yellow Toad gives the cards to the players and before the 1st minigame, Bowser shows up and gives this card to a random player. That player must get rid of the card within three turns, otherwise they will receive a Bowser Penalty, which effects include the following: go backwards a certain number of spaces, return to last place or a funny event (eg. Receive a lifetime supply of cotton candy!) that won't happen. The player is sure to have the malicious card when a Bowser light is circling on the touch screen. To get rid of it and pass it on to another player, they must hope the player in question draws the card randomly while trying to draw another. Another way to pass the card is triggering a certain event that forces the player that activates it to take the card.

Every 3 Turns
After 3 turns, the following happens: Then this process repeats after another 3 turns.
 * 1) Bowser Penalty activates to the player who has this card.
 * 2) Every other player loses the card they currently hold.
 * 3) A new set of cards, including the Bowser Card, are given.
 * 4) Another minigame takes place.

Effect on the Final Challenge and the Final Results
The player who holds the card can't take part in the end game, as Bowser won't let that player even try.

Also, when someone wins, Yellow Toad declares who won the game, followed by the ones below:

Bowser

 * "Oh, hello. Don't mind me! I'll just slip a Bowser Card into the deck and be on my way. BWAHAHAHAHA!"
 * "BAH! Nobody apologizes on my behalf! I'll be back in 3 rounds with a fiendish surprise for the player with my card!"
 * "Well, hello! I do believe it's penalty time! Let's see who has my precious Bowser Card..."
 * "Whoops! You have the Bowser Card, and that means you can't participate in the Final Challenge. BWAHAHA!"
 * "That must be so disappointing. Like I care! Hurry up and go back 3 spaces. I command it!"

Yellow Toad

 * "And (Bowser Card holder) had the Bowser Card. Sorry, (Bowser Card holder), but that means you automatically get last place."

Trivia

 * This could be a successor of Bowser's Bogus Items, a collection of Bowser-made items that appear in the original Mario Party.
