Master Necky

Master Necky is a giant Necky and the boss of the Monkey Mines in Donkey Kong Country. He is the second boss of the game. In battle, Master Necky spits coconuts at Donkey and Diddy Kong. To defeat this enormous bird, Donkey or Diddy must use the bouncy tire in the middle of the bird’s banana lair to Jump up high and stomp Master Necky’s head. After five hits, Master Necky collapses, and Donkey Kong recovers a Giant Banana.

In the Game Boy Advance remake, Master Necky was bright red before and after he attacked. The Kongs can't damage him until he spat out a coconut, showing his normal color, but he'd turn red again as he left the screen.

Trivia

 * The player never gets to see Master Necky’s whole body; only his head appears on the screen.
