Cactus King

The Cactus King was a giant Kong with a cactus-like object on the back of his head. It is unknown which land he rules. The Cactus King was in Donkey Kong: Jungle Beat after fighting Ninja Kong. Donkey Kong fought him, much differently than the previous battles, as Cactus King was roughly ten times his size. After collecting enough Crests, Donkey Kong traveled through what appeared to be the same level Cactus King lived in. However, when Donkey Kong reached the end of the level, instead of the Cactus King, he found Ghastly King. Ghastly though, looked exactly like the Cactus King having no differences except for a few new moves. It's possible Cactus King and Ghastly King were even the same person but this is not confirmed.

Battle
At the beginning of the battle, Donkey Kong sees Cactus King on a giant Hawg. Once the battle begins, the Hawg begins to breathe out fire. Donkey Kong must clap at the fire until he can approach the Hawg. Then, he must clap on the Hawg and stun it. Next, Donkey Kong must jump and start attacking the Hawg's snout. Once Donkey Kong has landed enough blows on the Hawg, Cactus King will jump and crush the Hawg. Donkey Kong must wall jump onto Cactus King's head and start pounding on it. If Donkey Kong does this enough, Cactus King will fall to Donkey Kong's might.

Trivia

 * At the very beginning of Cactus and Ghastly King's theme song is a remix of the song that played on the title screen of the original Donkey Kong.
