Kleever

Kleever, called Kleaver in Donkey Kong Land 2, is a levitating sword who appears in both Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. It is the boss of Crocodile Cauldron in the former and Krem Cauldron in the latter. It resides at Kleever's Kiln (Kleaver's Kiln in Donkey Kong Land 2).

Donkey Kong Country 2: Diddy's Kong Quest
Kleever emerges from the lava and throws three fireballs at Diddy and Dixie. A kannonball then collapses from the sky. It is used as a projectile against Kleever. If thrown at, it shakes and flashes red. Hooks collapse from the sky, their purpose being for the Kongs to cross to the other side of the boss level. This process has to be repeated two more times. If done, Kleever submerges into the lava and then suddenly emerges from the lava. It then charges itself at Dixie and Diddy. A kannonball then appears. Once it is thrown at Kleever, the monkeys have to cross to the other side. Kleever then charges once again at Diddy and Dixie. When the kannonball is thrown at Kleever, it slices at Diddy and Dixie, who have to reach the opposite side once more. This process has to be repeated two more times so that Kleever explodes into tiny pieces. Diddy and Dixie then earn a Kremkoin and are granted access to Krem Quay.

Donkey Kong Land 2
When the battle starts, Kleever is immobile, only slicing up and down. It then shoots fireballs at the controlled Kong. After shooting the fireballs, Kleever heaves a barrel with a kannonball inside. The barrel has to be jumped on to reveal a kannonball that must be thrown at it. If done so, Krocheads emerge from the lava. The active Kong has to cross to the other side with the help of the Krocheads. At the other side Kleever once again shoots fireballs and a barrel with a kannonball inside. When it is hit again the active monkey has to once again cross to the side opposite. When the active Kong reaches the other side, Kleever develops a new tactic: charging itself at the active monkey. The active Kong has to jump over it for a kannon to appear. Kleever then floats back and forth. The kannon has to be touched at the precise moment for a kannonball to be set off and hit Kleever. This has to be done once more so that the Kongs are awarded with a Kremkoin and are granted access to Krazy Kremland.

Trivia

 * Two Banana Coins can be found to the upper right corner of Kleever's Kiln. It can be accessed by a helicopter twirl done at the top-left part of the hooks.
