The first major boss of Mario + Rabbids Kingdom Battle, Rabbid Kong is obviously a parody of Donkey Kong. Unlike some other Spawny creations, he's not a fusion of a rabbid and Donkey Kong. But they seem to go to the same tailor for neck-ties.
I wouldn't say he's a difficult boss. But not knowing to jump on the banana panel to get rid of his supply confused me at first so I had to restart the battle over. His wave attacks are plenty annoying however.
But it isn't that difficult to take him down and have him falling to his doom.
