Plus and Minus Barrels

Plus and Minus Barrels make an appearance in only one level of Donkey Kong Country 2: Diddy's Kong Quest, "Haunted Hall".

A Plus Barrel has a green plus sign on the barrel and is used to increase the time on the timer in the level.

A Minus Barrel has a red minus sign on the barrel and is used to decrease the time on the timer in the level.

Additionally, a single Plus Barrel can be found at the begining of "Rickety Race". This Plus Barrel works differently; it speeds up the Kongs' Skull Cart.
