Iron Barrel
A Steel Keg (also known as a Steel Barrel) is a type of Barrel seen in the Donkey Kong series. They first appear in Donkey Kong Country, and are a staple barrel in the series (although they do not appear in Donkey Kong Country 2: Diddy's Kong Quest). This metal barrel is one of the most powerful weapons used by members of the Kong Family. The Steel Keg can be picked up and thrown in the same manner as a normal wooden Barrel; however, the Steel Barrel does not break upon contact with an enemy or a wall (as it is made of steel, not wood). Instead, the metal barrel will keep on rolling, bounce off walls, and continue to roll on the ground until it falls into a gap or hits a powerful baddie. The Steel Keg will destroy most any enemy it rolls into; as such, it can be used to take on entire chains of baddies. The Kongs can even jump on top of the barrel and ride with the weapon as it plows through enemies. Steel Kegs are also reusable, as a Kong can pick up a thrown barrel as it rolls by (and thus carry the barrel to a new location and throw it again). Steel Kegs are found scattered throughout Donkey Kong Island and the Northern Kremisphere.
Steel Kegs are needed to defeat Koins in the game Donkey Kong Country 3: Dixie Kong's Double Trouble and Donkey Kong Land III. The Kremling's DK Coin shield deflects any weapon thrown at it. As such, a Koin can only be attacked from behind; however, it always hold its shield between itself and the Kongs. Since the Steel Keg does not break upon hitting a wall, the Kongs can bounce the metal weapon off a wall behind a Koin to destroy it and claim its DK Coin.
The Kremlings known as Bazukas are the only known enemies that use Steel Kegs in combat. Some Bazukas fire Steel Kegs out of their bazooka-like weapons. A Kong hit by a fired Steel Keg runs away from its partner (or lose a life if alone). However, the Kongs can jump on top of the metal barrels and not be injured. In fact, the Kongs often need to hop from barrel to barrel to cross large gaps and pools of lava.
In the game Donkey Kong 64, three Steel Kegs appear in a mill in Fungi Forest. Chunky Kong needs to destroy these three barrels using a grinder (within a time limit) to obtain a Golden Banana. Steel Kegs also appear in the game Donkey Konga, where, in a certain minigame, the player uses a Steel Keg to bash King K. Rool in the head.
Steel Kegs appear in DK: Jungle Climber, as obstacles instead of items. Found floating in the air, these Steel Kegs can block passages and can only be destroyed by using Diddy Kong's hammer, detonating a TNT Barrel near it, or throwing a Bomb at it. Steel Kegs appear in the racing game Donkey Kong Barrel Blast. They appear, once again, as obstacles, though renamed Iron Barrels, mainly to trick the player into thinking they are regular barrels.
