Donkey Kong

Donkey Kong is the first miniboss encountered in Double Drabobo, and the first overall miniboss faced in Abobo's Big Adventure

Origin
Donkey Kong appears in the arcade game Donkey Kong, where he is the main villain. He kidnaps Mario's girlfriend, Pauline, and angrily carries her to the top of a high construction site. He is pursued by Mario and attacks him by throwing Barrels and creating living Fire. He is eventually pursued to the top of the construction site, where Mario causes the bars supporting him to crash, sending him to the ground.

In Abobo's Big Adventure
In Abobo's Big Adventure, Donkey Kong appears as a miniboss in Double Drabobo. He's the first miniboss in the game. He spawns on top of a building with broken ladders and a silver door, where Kid Niki, Chin Salabim and two Goombas ambush Abobo. While he is fighting them, Donkey Kong throws barrels at him. These barrels deal moderate damage and knock back Abobo if he gets it by them. A shadow appears below the spot where the barrels will land, making them easy to dodge. Once all the other enemies have been defeated, the lower part of the ladders will appear and Abobo will be able to climb them and defeat Donkey Kong. After Donkey Kong has been defeated, DK Jr. will exit from the silver door, only to hide again 4 seconds later.

Trivia

 * Nintendo has confirmed that, in the arcade game, Donkey Kong is actually a younger version of Cranky Kong, the grandfather of the actual Donkey Kong.
