Donkey Kong

Disaster in Delfino Jungle
Fought in Delfino Jungle, you will go up against Donkey Kong right as you enter the kingdom. He will take three hits like most Mario bosses.

Attack Mode
Donkey Kong will swing on the vines above you and try to grab you out of the air. Banana peels will also be randomly falling from the canopy, so watch out for their shadows. You can make him fall by cutting all of the vines with Cappy. When he’s on the ground, land a hit by jumping onto his head.

Defense Mode
Donkey Kong will jump up and down rapidly, and his stomps will cause more bananas to fall. Avoid these and wait for him to go back up into his vines to attack him again.

Alternatively, you can end the defense mode faster by climbing up and tree and jumping onto his head. This will skip the defense mode and go straight back into attack mode to finish the fight faster.
