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.

At the start of the game, after Toad gives the cards to the players, 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. Either way, after 3 turns, the Bowser Penalty activates, and a new set of cards, including the Bowser Card, are given. Furthermore, the player who holds the card at the end of the game will automatically be in last place as stated by Toad, and can't take part of the winning game, as the Shy Guys won't let that player even try.
