King Zing (Japanese: キングＢ, King B) is the boss of Krazy Kremland in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. He appears in the levels Rambi Rumble and King Zing Sting. When Diddy and Dixie Kong first enter the level, they see a Squawks Barrel that they must jump into to transform into Squawks and fight King Zing, making him first boss in the series to be fought against using an Animal Buddy.
King Zing appears near the end of the level. Here, he begins to chase Diddy and Dixie, who have transformed into Rambi, upon reaching his location, and chases him until he reaches the end of the level. In Donkey Kong Land 2, King Zing does not appear on this level.
King Zing Sting
In order for Squawks to score a hit on King Zing, he has to hit King Zing's stinger with his eggs. After an egg hits King Zing, he starts to flash yellow and red before returning to normal, resuming his normal patrol around the level, but going a little faster. If Squawks hits him again, he turns red and starts chasing Squawks while shooting out stingers in all directions three times before returning to his normal state.
After Squawks hits him in the stinger a few more times, he transforms into a normal Zinger, turns red and shields himself with four yellow Zingers that surround him. King Zing then starts to chase Squawks again. Squawks has to defeat all four of the Zingers. Once they are all defeated, King Zing becomes a yellow Zinger and it takes three more hits to finally defeat him. If he isn't quick enough at defeating all of them, the yellow Zingers then regenerate.
In Donkey Kong Land 2, the battle with King Zing is similar, but after being struck, he will not fire stingers, and instead will home in on Squawks while invulnerable, before returning to his normal zig-zag flight pattern. After being struck a few times however, King Zing will begin to spawn normal Zingers. These Zingers will appear behind him as he moves and will remain stationary. They will shortly disappear, and act as obstacles during the battle as King Zing gets faster and faster with each hit, continuously spawning Zingers.
In the Game Boy Advance remake of Donkey Kong Country 2: Diddy's Kong Quest, the King Zing battle is hardly changed. The only differences are that King Zing is slower and his stingers are faster. Also, his stingers in the remake only make one sound per blast, instead of an echoing sound.
