King Zing Sting (Donkey Kong Country 2: Diddy's Kong Quest)

King Zing Sting is the boss level of Krazy Kremland, the fourth world of Donkey Kong Country 2: Diddy's Kong Quest. To open access to the fifth world, Gloomy Gulch, Squawks must take down the giant Zinger, King Zing. This is the first boss in the Donkey Kong Country series to be fought by an Animal Friend.

Overview
The battle takes place in a hive. The Kongs start in a small, enclosed area next to a Squawks Barrel. This area contains two hidden Banana Bunch Coins. There are three bananas on the way into the arena proper.

King Zing flies across the stage in a pattern, moving horizontally until he reaches a side, moving up or down a bit, then flying back to the other side again. Squawks must hit King Zing's red stinger with eggs to damage him. Each hit will cause him to move faster, and after the second and fourth hits, he will temporarily turn red. In this state, he will shoots three sets of spikes in eight directions while slowly advancing toward Squawks, then rise to the top of the arena and resume his normal flight pattern. After six hits, he will shrink to the size of a normal Zinger, turn red, and summon four other Zingers to assist him. He will then start chasing Squawks while the Zingers circle around him. Squawks must defeat the four Zingers to make King Zing vulnerable again; if he does not beat them fast enough, they will respawn. Once all of them are gone, King Zing reverts to his normal color scheme, and three more eggs will take him down. He drops a Kremkoin when defeated.

In the Game Boy Advance port, King Zing moves slower, his stinger shots move faster, and he takes one more hit to defeat in his last phase.
