Krizossaurus

Krizossaurus is a giant green dinosaur-like creature which first appeared as a boss in the DKC4 the Kong's Return demo as the boss of Kiddy's Hideout and has again appeared in Donkey Kong Deluxe: Adventures on DK Island as the first boss of the game and the boss of Kongo Jungle in Krizossaurus Karnage.

Krizossaurus is quite a unique boss in the game, although he wasn't that unique in DKC4 where he just moved back and forth.

Summary
Krizossaurus can be found at a small island across a wide stream of water connected to a waterfall. When the kongs enter the stage, a cutscene starts, where the kongs disturbed him from his nap and woke up to try and drive them away. First, he jumped out, roared at them and spat out a coconut at them to hit.

The Kongs avoided the attack and started to fight him too. Then the battle begins. Krizossaurus' main attacks are to spit coconuts at them like Master Necky spat large nuts from DK (Donkey Kong) Country and moving back and forth. There is also a tire on the left of them. The Kongs need the tire to jump and attack him and also to avoid the coconuts that he spits.

Once you defeat him, another cutscene happens where he starts to get dizzy. Then, he lets out a deep loud roar and then falls on his back. Then the fight ends and the Kongs move on.
