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.

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

Mega Mushroom
Become mega and roll two dice blocks. You will take 10 coins from every player you pass, but you skip board events and stars.
 * Price: 5 coins

Super Mini Mushroom
Become mini and roll two dice blocks. They are still limited to 1-5.
 * Price: 15 coins

Super Mega Mushroom
Become mega and roll three dice blocks.
 * Price: 15 coins

Mini-Mega Hammer
A randomly chosen player becomes mini or mega. You cannot use it on yourself.
 * 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 attacks you, he won't be able to steal anything from you. 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 Star will move when you use this item. 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: N/A

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 25, so this is a bad buy. However, it is a good prize in Mini Mini-Games.
 * 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
