Krow

Krow is the name of a large Mini-Necky boss who wears a black pirate hat, who is encountered in the game Donkey Kong Country 2: Diddy's Kong Quest.

Donkey Kong Country 2
After Diddy and Dixie Kong ventured through the rapidly decaying ship, Gangplank Galleon, they manage to reach the ship's Krow's Nest, where they encountered Krow. The giant vulture's most commonly used tactic is to pick up one of his eggs and hurl it at the Kongs, though he will also swoop down to attack his foes on occasion.

Krow's careless use of his eggs as weapons will prove to be his undoing, as the Kongs can grab an egg once it stops bouncing and throw it at Krow, injuring him. After being hit multiple times, Krow will become disoriented and begin to bash into his nest, flinging eggs everywhere. Diddy and Dixie must avoid these falling eggs and grab the ones that stop bouncing and hurl them at Krow, who becomes even more eratic. After being hit by a few more eggs Krow will finally collapse, surrender the Kremkoin he was guarding, and die.

Unfortunately for Diddy and Dixie, this was not the end of Krow. After traveling through the phantom infested area, Gloomy Gulch, Diddy and Dixie came upon what appeared to be a dilapidated crow's nest. Venturing onto this structure, the Kongs encountered the ghost of Krow. This time, "Kreepy Krow" would send a barrage of ghostly Mini-Neckies against the Kongs, who must avoid these spectral birds and jump on the sole living Mini-Necky deployed by Krow. This will summon a barrel which the Kongs can hit Krow with, causing him to fly upward. After this, a hook will drop nearby, and the Kongs must use this hook to reach some rigging. After climbing the rigging and dodging eggs thrown at them, the Kongs will reach the platform where Krow awaited them. The phantom vulture will once again send a barrage of ghostly Mini-Neckies at the Kongs, but this time the speed and number of Mini-Neckies increases. The Kongs must once again jump on the living Mini-Necky to make a barrel appear which they can throw at Krow.

After being hit by this barrel Krow will once again fly upwards and the Kongs must follow; and after dodging numerous eggs, they reach the top of this exceedingly tall crow's nest. Here, Krow sends another barrage of ghosts after the Kongs, who defeat the living Mini-Necky and throw the resulting barrel at the ghostly vulture, defeating Krow once and for all.

Back Again?
In Donkey Kong Land 2, Krow inexplicably appeared as the living boss of Gangplank Galleon, and also reprises his role as Kreepy Krow of Gloomy Gulch. Whether this is the same Krow as the one in Donkey Kong Country 2 or is simply another Krow is unknown.

Trivia

 * In the Game Boy Advance remake of Donkey Kong Country 2, a short animation of Krow's spirit leaving his body can be seen after he is defeated for the first time.
