Warp Barrel

Warp Barrels are uncommon types of barrels from the latter two Donkey Kong Country and Donkey Kong Land games. They are usually distinguishable from the "W" painted on them. As their name suggests, Warp Barrels warp the Kongs to the stage's goal. Warp Barrels are usually hidden off-screen or in out of reach areas. A Warp Barrel is invisible until the Kongs enter into it. Warp Barrels are optional and the Kongs are not required to enter them to finish a level.

In Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Country 3: Dixie Kong's Double Trouble!, a Warp Barrel appears in every level of each game's first two worlds (Gangplank Galleon and Crocodile Cauldron in the second game and Lake Orangatanga and Kremwood Forest in the third game).

Donkey Kong Country 2: Diddy's Kong Quest / Donkey Kong Land 2
Warp Barrels appear in Donkey Kong Country 2: Diddy's Kong Quest with the appearance of a Barrel Kannon in the Super NES version. When entered, Diddy and Dixie are sent into a warp room. The warp room usually only takes up a single screen, and in the center is a group of bananas in the shape of a large exclamation mark. The Kongs can exit out of the warp room to their right.

In Donkey Kong Land 2, Warp Barrels have the same sprite as Bonus Barrels. Unlike Donkey Kong Country 2: Diddy's Kong Quest, the warp rooms do not have bananas shaped like an exclamation mark. Warp Barrels only appear in levels from the first world, Gangplank Galleon.

Donkey Kong Country 3: Dixie Kong's Double Trouble! / Donkey Kong Land III
In Donkey Kong Country 3: Dixie Kong's Double Trouble!, Warp Barrels have a "W" decoration on them. Unlike the previous game, Dixie and Kiddy are not sent into a warp room, so by entering the Warp Barrel, the Kongs are instantly warped in front of the Level Flag.

In Donkey Kong Land III, unlike Donkey Kong Land 2, the Warp Barrels are marked with a "W". Unlike Donkey Kong Country 3: Dixie Kong's Double Trouble!, the Warp Barrels take the Kongs to a small warp room, which they can exit from the right to reach the End of Level Flag.

Donkey Kong Country
In the Game Boy Advance remake of Donkey Kong Country, Warp Barrels replace the Blast Barrels from the Super NES and Game Boy Color versions that send Donkey and Diddy Kong near the end of the level. They are much more common than the original barrels, appearing once per level. Warp Barrels were redesigned with the "W" on a red explosive effect; this design also appears in the other two Game Boy Advance remakes. By entering a Warp Barrel, the Kongs are taken to a space with its own music track that does not exist in other versions of the game - an ice walkway in a black void, with pictures of some levels, each showing a different environment, hovering across in the background. On the icy path there are bananas that spell out "WARP", and the end of the scene puts the Kongs near the end of the level. In all versions of the game, Stop & Go Station has an off-screen warp point that functions as one of these barrels, which is found by walking into the entrance to the left at the very start.

Trivia

 * While Donkey Kong Land does not have any Warp Barrels, a few levels have a hidden alternate exit at the very start: Arctic Barrel Arsenal, Sky High Caper, and Skyscraper Caper.
