Bowser's bogus items

The title of this article is conjectural; an official name for the article's subject has not been found, so it has been given a fitting title by the editors. If an official name is found, then the article should be moved to its appropriate title.

Bowser's bogus items are useless items forcibly sold to partiers by Bowser in Mario Party when they pass him on a board. On Luigi's Engine Room and Wario's Battle Canyon, he does not sell the player an item, but instead provides them with some worthless "service."

Bowser does not sell any useless items or provide a worthless service on either Bowser's Magma Mountain or Eternal Star, where he steals either a Star or 20 coins if they don't have at least 1 Star. He won't do anything if the player doesn't have any coins or Stars.

In Mario Party Superstars, Bowser will sell either the relevant item for the board he is encountered on, or a Cursed Dice Block for 11-20 coins instead.

Board	Item/service	Description
DK's Jungle Adventure	Gold-plated Bowser Statue	Bowser sells this item to players for 10 coins. It looks like a miniature version of the Koopa King, and is completely worthless. A version of this statue also appears in Mario Party 6 and Mario Party 7.
Peach's Birthday Cake	Bowser Cake	When a player gets a flower with Bowser's face on it in the Goomba lottery, they are sent to Bowser, and he forcibly gives the player this item for 20 coins. It is just a spiked shell with a candle and frosting, and cannot be eaten. In Mario Party Superstars, Bowser states that the cake is made out of rocks. In the last game, Bowser can give a Cursed Dice Block by paying him 11-20 coins, or King Koopa might give coins to the player if they are in last place with 0 coins.
Yoshi's Tropical Island	Bowser Tube	Bowser creates an inner tube that he says will allow the player to help the Yoshi and travel over the whirlpools. However, upon being put on the player, the inner tube shrinks and then bursts around the player. Bowser demands 30 coins for buying (and in this case, popping) his merchandise, making it the second most expensive bogus item. Like Peach's Birthday Cake, in Mario Party Superstars Bowser may give a Cursed Dice Block for 11-20 coins to the player. He will also give coins to the player if they are in last place with no coins achieved.
Wario's Battle Canyon	Bowser's Claws	Bowser says he will shoot the player from his Bowser Cannon, but instead uses his claws to blast the player to a random area of the board (ironically, the cannon itself is never fired until the end of the game, where the last place player is launched out of it). The player will pay 20 coins (or all their coins if they have 20 or less) for the ride. Bowser can also give the player ride for free, if they have zero coins.
Luigi's Engine Room	"Make As Many Coins As You Want Mecha"	Bowser activates this machine in order to create a coin for the player at the cost of 20 coins, thus meaning the player loses 19 coins, due to the one coin they get from the machine. Unlike other bogus items, the player character is shown to be glad over the turn of events, mostly because they at least got a coin back.
Mario's Rainbow Castle	Ztar	Bowser forces the player to buy a Ztar. Unlike Ztars later in the Mario Party series, this one does not count as a negative star. However, the Ztar costs 40 coins as opposed to a regular Star costing 20, making it the most expensive of the bogus items. It should be noted, though, that immediately after "buying" the Ztar, the player will pass Koopa Troopa and earn back 10 coins (20 in the last 5 turns or if it is the 10th time someone has passed Koopa Troopa; 30 for the 20th time; 40 for the 30th time and etc).
