Spinner Barrel

A Rolling Barrel, also called Rotatable Barrel,   Rotater Barrel or Spinner 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.

Rolling 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 Barrel. After this limit, the Kongs will be launched automatically. Steerable Barrels are similar, except that their aim cannot be changed, and the player can move them around instead.

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