Plus and Minus Barrels are a type of Barrel unique to Donkey Kong Country 2: Diddy's Kong Quest. Plus and Minus Barrels are only found together in Haunted Hall. Their primary purpose is to increase or decrease the time when a Kackle would attack the Kongs. In Haunted Hall, as a Kackle begins to chase a Kong, a timer begins and as it depletes, the Kackle draws closer, until zero, where it injures a Kong. By breaking a Plus Barrel, the timer will increase, keeping Kackle away. However, the opposite happens when Minus Barrels are collected, and should thus be avoided.
A secret Plus Barrel can be found in Rickety Race by reversing the Skull Cart as soon as the race starts. It would give the player a significant speed boost, making it easier to defeat the Klanks, and finish the race in first place sooner.
- The original DKC2 manual claims the minus barrels will take them to the "Minus world", a reference to a famous glitch found in Super Mario Bros.
- A number of connections can be made with Donkey Kong Country's Stop & Go Barrels of Stop & Go Station; the barrels both appear exclusively in that one level, are needed to disable invincible enemies (in DKC's case, Rockkroc, and both provide a temporary effect in disabling the foe (the latter in Plus Barrel's case).
