Battle
Master Necky Snr. boss battle is almost the same to Master Necky's but instead of spitting out just one coconut so Donkey Kong/Diddy Kong will be able to hit him, every time you hit him he spits out another additional coconut along with the first coconut he started with until he spits out a total of 5 coconuts at a time, and you can't give him a hit untill he's done spitting coconuts.
