Mangoruby

Mangoruby is the fifth boss in the game Donkey Kong Country Returns and Donkey Kong Country Returns 3D. He is the boss of the Forest area, appearing in the level Mangoruby Run. Mangoruby is seen sleeping peacefully before he is hypnotized by Panflute Tiki.

Physical description
While Mangoruby is normal, he has a yellow head with green leaves growing out of it. He has six pink body segments which are connected by green tubes. He also has purple eyes with black pupils and petal-like eyelids. Mangoruby also has green leaves for arms. When hypnotized, Mangoruby's segments become yellow and electrified.

Attacks
Mangoruby mainly attacks by chasing Donkey Kong and Diddy Kong around the arena (which only happens after the player hits the first switch, or else he will not show up). The boss chases the Kongs through all the twists and turns and will hurt them on contact. However, the Kongs will be safe if they stand on one of the various wooden platforms throughout the arena. Occassionaly, the boss will drop a ball of electrical energy that will split up into two surges going in opposite directions. If the Kongs touch the ball of energy, they will lose a heart.

Combat
To defeat Mangoruby, Donkey and Diddy must hit all five switches on the platforms to release the light. This will weaken the Tiki's control over Mangoruby and also unelectrify him. Donkey Kong and Diddy Kong must then jump on its pink segments to destroy them (two at a time). This must be done three times. After this, the Tiki will release itself from the body and will be vulnerable to Donkey Kong's attack.
