 Crate

Attack or throw a crate to break it open and gain access to the items inside. There are three designs for crates. Additionally, some crates have dollies underneath them. Attacking these crates sends them rolling away.

 Barrel

These bear a resemblance to crates but can tip over and roll. Barrels are pretty sturdy and can be a bit tough to crack open neatly.

 Capsule

Break open these little capsules to find items. They’re also effective as a throwing item. Capsules will explode on occasion.

 Party Ball

When hit, Party Balls float up into the air and split open, raining down a torrent of items. These items are known to drop nothing but Bob-ombs sometimes.

 Blast Box

Hit these with a strong attack or fire-based attack to detonate the blast box, causing a huge explosion that blows anything in the area away. If one of these pops up, your first move should be to keep an eye on any characters who can use fire-based attacks.

 Sandbag

Beat Sandbag up to make it drop items and food. As Sandbag accumulates damage, it gradually becomes easier to hit far distances. Of course, beat Sandbag too much and its pool of items will run dry.

 Food

Scoop food items up to lower your damage percentage. There are essentially 28 different types of food. Each item restores a separately designated amount of health. In addition to the types mentioned above, you can expect to chow down on other items like Peach’s peaches and Summit veggies.

 Maxim Tomato

These tomatoes are emblazoned with a striking letter "M." Eating one of these reduces your damage by 50 percentage points.

 Heart Container

Pick up one of these to reduce your damage by 100 percentage points. Heart Containers float slowly to the ground once they appear, but don’t risk waiting around for them to hit the ground—jump up and grab ‘em in midair. You should also know that the three Heart Containers that appear in All-Star Mode heal all accumulated damage.

 Dragoon Parts

Gather all three pieces to assemble the legendary Air Ride machine called the Dragoon.

 Super Mushroom

Pick one of these up to grow huge. In your enhanced form, you won’t fly as far when hit and are capable of dealing harder-hitting blows than usual.

 Poison Mushroom

These are hard to distinguish from Super Mushrooms. Pick one up and you’ll shrink in size, your blows will do less damage, and you’ll fly further when hit.

 Warp Star

Take a ride on a Warp Star to launch a vicious attack from above on the opponent. You can control where the Warp Star falls by using your Control Stick.

 Starman

Just touch one of these and you’ll gain temporary invincibility. The effect lasts 10 seconds.

 Metal Box

Turn metal and gain no-flinch resistance to lighter attacks. Just be aware that you’ll fall like a rock.

 Bunny Hood

The Bunny Hood provides a substantial boost to your running speed and jumping power. Plus you get rabbit ears, which makes your character look adorable.

 Superspicy Curry

Eat one of these and the flames just won’t stop. You can, however, continue to attack as normal. This item also has the side effect of making you run even if you try to walk.
Read more here.

 Timer

Pick up this item to slow down the flow of time for all other players. Occasionally the Timer will have a different effect and only slow you down, or it may slow down everyone.

 Lightning

Touch one of these and all of your opponents will shrink. The effect is more dramatic and dangerous than the one brought on by a Poison Mushroom. Sometimes the Lightning will backfire and only your character will shrink.

 Beam Sword

Grab one of these and your sideways attacks will all change to use the Beam Sword. The stronger the attack, the longer the beam of the sword will be.

 Home-Run Bat

Perform a side smash while holding this item to take a home-run-sized swing at the opponent that sends him or her soaring. The Home-Run Bat is also your friend in the Home-Run Contest mode. It’s strong when thrown too.

 Fan

This item doesn’t pack much of a punch but is easy to score rapid multiple hits with—it can also break shields. The Fan has deceptive strength when thrown straight up in the air in modes like Multi-Man Brawl.

 Lip’s Stick

Hit an enemy with this or throw it to make a flower bloom on the opponent’s head. While the flower is on his or her head, the opponent will slowly accumulate damage. The more you beat your foe with Lip’s Stick, the bigger the flower on his or her head will grow.

 Star Rod

Perform a strong side attack or side smash attack while holding the Star Rod to swing the rod and simultaneously fire off a star-shaped projectile. It’s both a battering and throwing item. When you throw a Star Rod at the opponent, it sends them rocketing off sideways.

 Hammer

Seize this item to unleash a barrage of hammer swings on the opponent. The attack itself is quite powerful but you’ll lose the ability to perform midair jumps and special moves while attacking with it. Sometimes the head of the hammer will pop right off.

 Golden Hammer

This rare hammer appears every once in a while. Repeatedly press buttons in midair to float while the hammer is in use.

 Super Scope

This beam gun let’s you choose between attacking with rapid-fire and charged shots. The Super Scope holds enough energy for 48 rapid-fire shots, or about three fully charged blasts.

 Ray Gun

The Ray Gun is a beam gun that lets you fire fast moving blasts. It comes loaded with 16 shots. When you’ve exhausted your rounds, shooting items remain useful since you can throw them at the opponent to score a smash attack.

 Fire Flower

The Fire Flower is a shooting item that spouts a torrent of fire over a short distance. Take care that you don’t direct the flames into a PSI Magnet, which will absorb the attack.

 Cracker Launcher

Change the angle of fire by moving the barrel up and down, then let off a stream of fireworks. Tap the direction opposite your current facing to turn around. Also, know that you can tell when you’ve fired the last shot in the Cracker Launcher by the smoke, which is a different color than the other shots.

 Bob-omb

A simple and powerful bomb. The power of this thing earns top marks. If you leave it alone it will get up and walk around on its own. Once enough time has passed in Sudden Death, Bob-ombs start to fall from the sky in droves.

 Motion-Sensor Bomb

Set one of these on the floor or wall and it will react to the next moving object in its proximity by detonating. These guys are small and inconspicuous, so try setting one as a trap.

 Gooey Bomb

Gooey Bombs stick to the opponent and blow up once a set amount of time has passed. If someone sticks one to you, you should make it a priority to pass it back to them.
Read more here.

 Smart Bomb

Throw a Smart Bomb and it will burst into a massive explosion that pulls enemy and friend alike into the blast, scoring multiple hits. Every once in a while you’ll come across a dud smart bomb, too.
Read more here.

 Deku Nut

Peg the area near an enemy with one of these to make them dizzy. When the Deku Nut makes contact with an opponent in midair, it can send them quite a distance. When you strike with a Deku Nut, make sure you don’t get caught in the explosion.

 Freezie

This icy item slides slowly along the ground. Throw it at the enemy to freeze them in a block of ice, trapping them. You’ll want to hammer on the buttons and wiggle the Control Stick to get out of that ice as fast as you can.

 Smoke Ball

Smoke issues with a hiss from this item and obscures the area. You can slap one of these on your opponent or yourself.
Read more here.

 Pitfall

Set one of these on the ground and watch as your opponents stumble into it, burying themselves in the floor. This throwing item has a meteor smash effect when you throw it at an airborne opponent.
Read more here.

 Hothead

Hotheads slide across the ground releasing bursts of sparks and damaging your opponents. What’s more, when hit with fire or electricity-based attacks, they grow even bigger!

 Mr. Saturn

When you throw Mr. Saturn into a solid object, he gives a little cry of "puuu!" He’s more of a mascot character than anything else, but he’s fairly good at breaking shields.

 Green Shell

Throw, hit, or jump on this shell to send it sliding along the ground. Green Shells can suddenly reverse the direction they are traveling if they bump into a wall or are hit by an attack, so keep an eye out for returning shells.

 Banana Peel

The item positively begs for you to slip on it. If you step on a Banana Peel your character will fall on his or her backside.
Read more here.

 Bumper

A pinball bumper. Set this Bumper on the ground or in the air and watch it bounce opponents who make contact with it down and away.
Read more here.

 Spring

Hop on a Spring to perform an extra high jump. Every so often a Spring will topple over sideways. When it does so, anyone who makes contact with the fallen Spring will be knocked sideways.

 Unira

Throw an Unira into the ground or attack it to cause its spikes to extend and damage opponents who bump into it. Attack the Unira again to make its spikes retract. Unira comes to Brawl from Clu Clu Land.

 Soccer Ball

You can’t pick up this item but when you hit the ball with an attack, it bursts into flames and zips off into the air. The angle of your attack determines the direction the Soccer Ball will fly off in, so aim well before you shoot.

 Team Healer

This item is designed for Team Brawl use. Throw it at your opponent to reduce their damage percentage. Hitting enemies with a Team Healer may damage or heal them depending on the circumstances.
Read more here.

 Franklin Badge

Just slapping this handy item on your chest causes all incoming enemy projectiles to be repelled. There’s no disadvantage to having one on, so if you see a Franklin Badge, grab it!
Read more here.

 Screw Attack

This is another item that you wear. While wearing it, the Screw Attack ability is added to your standard and midair jumps. You’ll still be able to attack as normal during the Screw Attack, which means you’ve got the potential to create chains of attacks in some unexpected combinations.

 CD

CDs add a single song to the song collection you can access through the Sound Test and My Music modes. CDs will stop appearing once you’ve unlocked every song in the game.
Read more here.

 Trophy

Sometimes single trophies will appear as well. Grab this item to add a trophy to your collection.
Read more about trophies here.

 Sticker

Character stickers. Other than their obvious purpose as collectibles, stickers serve as a means to power up your character in The Subspace Emissary.
Read more here.

 Key

These open the locked doors you’ll encounter within Adventure Mode: The Subspace Emissary. If you lose a key you were holding on the way to the door, just return to where you originally found it. By the way, these guys pack a real punch when thrown.

 Trophy Base

Use these to turn enemies into trophies in Adventure Mode: The Subspace Emissary. Hold off on throwing the base at an enemy until it’s been sufficiently weakened.
Read more here.

 Stock Ball

This item is known as a Stock Ball. In Adventure Mode: The Subspace Emissary, Stock Balls increase the number of lives you have left. There’s no downside to picking these up, so don’t pass them up.

 Coins and Bills

These special items appear when playing Brawl under the Coin rule. Bronze coins are worth one point, silver are worth three, gold are worth six, and the bills are worth 10. These are different than the coins you use in the Coin Launcher and Spectator modes.
