Krow is quite a unique that an undead version is later fought later in the game known as Kreepy Krow.
Krow can be found in the ship's crow nest. Krow appears to have settled in and made his own nest between the events of Donkey Kong Country and Donkey Kong Country 2. When the Kongs enter the nest, Krow will screech and fly up to his nest. He will then aim it on Diddy and Dixie must throw it at Krow. Krow will get desperate and ram himself into the nest in order to rain down eggs, which must be avoided. One should land, and be used as a projectile in order to defeat Krow when thrown at and gain a Kremkoin and move on.
In Donkey Kong Land 2, he will swoop in with an egg, and Diddy/Dixie must jump over him, and then he will drop the egg, which must be thrown at him. After doing this twice he rams into the mast and eggs rain down, and the last of it is an egg which must be grabbed and thrown at Krow to gain a Kremkoin and move on.
