Spinner Barrel

A Spinner Barrel, also called a Rolling Barrel, Rotatable Barrel,  or Rotater Barrel, is a type of barrel that first appears in Donkey Kong Country 2: Diddy's Kong Quest, where it first appears in the level Barrel Bayou. Spinner Barrels are similar to the Blast Barrel, although this type of barrel can actually be rotated and fired in any direction. However, some of them have a time limit (indicated by a number that appears on the barrel) to how long the Kongs can stay in the barrels. After this limit, the Kongs are launched automatically. Steerable Barrels are similar, except that their aim cannot be changed, and the player can move them around instead.

Spinner Barrels also appear in Donkey Kong Land 2, Donkey Kong Land III, DK: King of Swing, and DK: Jungle Climber, where there is no time limit regarding how long the Kongs can be in the barrels.
