Mario Party 4/Items

Items can be bought at the Item Shop, won in Mini Mini-Games, gotten from Mushroom Spaces, or won at the Lottery Shop. Each player can carry up to three items at a time. In team play, you can also use your partner's items.

Single Mini Mushroom
Become mini so that you can pass through pipes and play Mini Mini-Games. Your dice block will only roll 1-5.
 * Price: 5 coins

Double Mega Mushroom
Become mega and roll two dice blocks (for a total of 2-20 spaces). You steal 10 coins from every player you pass, but you skip board events and stars. Rolling the same numbers is 10 coins; while rolling two "7's" is 30 coins.
 * Price: 5 coins

Double Mini Mushroom
Become mini and roll two 1-5 dice blocks (for a total of 2-10 spaces). It's even possible to roll the normal number of spaces (2-10). But you can't roll a total of "1". Rolling the same numbers is 10 coins (for two "1's", two "2's", two "3's", two "4's", or two "5's").
 * Price: 15 coins

Triple Mega Mushroom
Become mega and roll three dice blocks (for a total of 3-30 spaces). Rolling the same numbers is 10 coins (for three 1's, 2's, 4's, 5's, 6's, 8's, 9's, or 10's). Rolling three "3's" is 30 coins, while three "7's" is 50 coins.
 * Price: 15 coins

Mini-Mega Hammer
A randomly chosen competitor gets their effect inflicted by either mini or mega (from either a Single Mini Mushroom or a Double Mega Mushroom) for their next turn. They will not be able to use an item (if they have any items in their inventory) on their next turn. You cannot inflict your own effect (mini or mega) with this item by hitting yourself on the head.
 * Price: 10 coins

Warp Pipe
Spin a roulette to determine which player you swap places with. These are useful when someone else is in range of the star or when you're the farthest player from the star.
 * Price: 10 coins

Swap Card
Spin a roulette to determine which player you swap items with. This is useful when at least two opponents have better item selections than you do.
 * Price: 15 coins

Sparky Sticker
Electrify the space you're standing on. The next player to reach the space will lose 10 coins and any mushroom effects.
 * Price: 15 coins

Gaddlight
If you have this item and a Boo (summoned by an opponent who has the Boo's Crystal Ball or summons him from a Boo House) attacks you, you can use this item and scare Boo away and he is unable to steal anything from you (and nothing for the opponent). The Gaddlight will then disappear. If you try to use the Gaddlight at the beginning of your turn, you will be asked whether you wish to discard it or not. This can be useful if you have two other useful items and nobody else is in a position to send a Boo after you.
 * Price: 20 coins

Chomp Call
The host and the Star Space moves when you use this item. Four Chain Chomps surround the host (when this item is used) and they scare them away to a different location. This is useful when somebody else is about to reach the star or the star is in a hard-to-reach spot.
 * Price: 15 coins

Bowser Suit
You have one dice block to steal 30 coins from each player you pass. These can only be obtained by landing on a Bowser Space. Your chances of getting one even then are still tiny.
 * Price: -

Boo's Crystal Ball
Lets you steal coins from another player for 5 coins or a star for 50 coins. The maximum number of coins the boo will steal is between 25 and 30 so this is a bad buy. However, it is a good prize in Mini Mini-Games. You can avoid the Boo by pressing "A" repeatedly (if the Boo steals coins) and you can lose less coins (the price for stealing coins is 5 coins). The Boo steals up to 30 coins. The less number of coins that can be lost is 9 or 10. The most is 25-30. However, if the Boo steals a star (for 50 coins), the option to tap "A" is absent. If you have a Gaddlight, however using the Gaddlight chases Boo away (when he is after your coins and stars).
 * Price: 25 coins

Genie Lamp
Takes you to the Star. You still need 20 coins to buy the Star. If it's available and you have 50 coins or more, buy it.
 * Price: 30 coins

Item Bag
The Item Bag contains up to three unknown items. You will get as many items as you have room for. It's best to buy this when you're out of items but not headed for a Mushroom Space.
 * Price: 30 coins
