Barrel

Barrels are one of the two weapons that Donkey Kong used against Mario in Donkey Kong arcade game. Since then, barrels have appeared in many other Donkey Kong and Mario games. But they are more common to appear in Donkey Kong games. Barrels can be picked up and used to attack Kremlings, Koopas, and other enemies.

Donkey Kong
In Donkey Kong, the first threat Mario ever faced was from a blue barrel that Donkey Kong threw in level 25m. When a blue barrel rolls into an Oil Drum, it will spawn a Fireball. Donkey Kong mostly throws brown barrels which Mario could jump over them (gaining 100 points) or smash them with his hammer like with blue barrels.

Super Mario Sunshine
Super Mario Sunshine included items known as Water Barrels, which could be broken open and used to refresh F.L.U.D.D.'s water supply, clear large patches of Graffiti, or to instantly cool things down.

Super Smash Bros.
Barrels also appear as items in Super Smash Bros. and Super Smash Bros. Melee, where they contain one to four items and can roll along inclines. They also sometimes explode when broken. It returns in Super Smash Bros. Brawl, alongside the Crate. This time around, it changes appearance depending on the stage. For example, it turns into a Present Barrel on the Yoshi's Island stage; the effect of the Barrel remains unchanged anyways.

Donkey Kong Jungle Beat
In Donkey Kong Jungle Beat, barrels were used to transport Donkey Kong to kingdoms. Barrels acted as worlds on the world map. There were four barrels, each linking to four different kingdoms. Each barrel had a letter in front with each letter spelling out the initials of Donkey Kong Jungle Beat. The D Barrel linked to the Banana Kingdom, Orange Kingdom, Watermelon Kingdom, and Apple Kingdom. The K Barrel linked to the Strawberry Kingdom, Pineapple Kingdom, Lemon Kingdom, and Grape Kingdom. The J Barrel linked to the Cherry Kingdom, Peach Kingdom, Melon Kingdom, and Durian Kingdom. The B Barrel linked to the Pear Kingdom, Lychee Kingdom, Chili Pepper Kingdom, and Star Fruit Kingdom. Completing all the kingdoms in each barrel would allow Donkey Kong access to the next barrel.

New Super Mario Bros. Wii
Barrels also appear in New Super Mario Bros. Wii. They can be carried and thrown by the player in order to defeat certain enemies. However, they can also harm other players if they get hit by one.

Donkey Kong Country Returns
Barrels reappeared in Donkey Kong Country Returns, where they can be used to take out enemies again.

Super Mario 3D Land
Barrels appeared once in Super Mario 3D Land, where at the final boss battle with Bowser, there is a point in the battle where Bowser throws barrels at the hero.
