Invincibility Barrel, which is also known simply as the ! Barrel, is a special type of barrel that allows the Kongs to be temporary invincible. It is introduced in Donkey Kong Country 2: Diddy's Kong Quest, and later appears in Donkey Kong Land 2 and Donkey Kong Country 3: Dixie Kong's Double Trouble!. The "!" on the barrel probably is to show the excitement of gaining invincibility (even if it is only for a short period of time).
In Donkey Kong Country 2, they are quite rare. They only appear in a few select levels, and in those cases, there is a sort of Bonus Barrel that can be found utilizing the invincibility. Any enemies who make contact with a Kong while invincible is be defeated.
